Maurice the “FrankenRuger” (Magazine Fed Revolver)

TFB is firmly committed to our “no politics” rule. That said, there are many innovating developments created that maximize effectiveness under restrictive laws. The “FrankenRuger” is one of those pistols.  The result is a magazine-fed revolver that is 100% California-legal without requiring entry onto the state’s approved-handgun list. 

**Note added 3/4/14: Jim March has joined into the comments below. He notes that the firearm was not designed to circumvent existing laws. Please note that this is a one-off prototype and not a production-ready design. 

Created by Jim March back in 2013, Maurice started as a Steampunk project and “went there on its own.” Jim describes the design of the revolver in detail on his YouTube page:

The manual ejector is gone. The barrel is multi-part: the rifled core is a 3.25″ section of Douglas Premium .355″ barrel threaded into the frame and with another thread at the muzzle. There’s a muzzle-end nut that compresses the stainless steel sleeve, pulling the barrel forward much like a Dan Wesson revolver and like a DW, the barrel/cylinder gap can be finger-adjusted. On top of the barrel nut is a gas trap that can be spun to adjust windage as it doubles as the front sight base. The gas trap bolts to the muzzle nut with a series of set screws. The gas trap dumps ejection gasses to the rear through the original frame mount for the ejector rod. On ejection shells hit a hammer-mounted deflector instead of my right cheek as in early tests :). The magazines use Wolff coil springs meant for a 32-20 levergun. Cylinder blank is by Bowen Arms, David Manson made my finish chamber reamer (wonderful smooth results!), the compression barrel sleeve is a section of handlebar from a 1980 Honda CB900c :). Copper and brass bits from a local Ace Hardware :). The magazine flat springs for retention are modified hacksaw blades with the teeth polished off.

The original thread for the pistol can be found on The Firing Line. 

Readers, what do you think? Will magazine-fed revolvers fill a niche role or is this a hair-brained one-off?

  • Rich

    Utterly hairbrained. And glorious.

    This breaks open the conspiracy. Haven’t you wondered why revolvers in Hollywood movies care fire more than 6 rounds? NOW YOU KNOW!

  • Anonymoose

    I’m not sure what I just watched…but I kinda want one. :3c

  • Phil Hsueh

    Ok, where are the almost obligatory solution to a non-existent problem posts that always seem to pop up?

    • Steve Truffer

      It was already stated to overcome a problem- California’s asinine laws.

      • jimmarch

        No, not exactly.

        I built it because I like how SA revolvers feel in the hand and their accuracy potential, but didn’t like the low ammo capacity and slow reload times…oh, and the crappy sights.

        I set out to fix the downsides while keeping the upsides.

        We ain’t even talked about the sights yet. What’s on there now is a handmade prototype of an unreleased design that I don’t own. Tim Sheehan does – this is a variant of the Goshen Enterprises “Hexsite” and I can’t say more than that or show you a shot down the sight tube.

        But it works about as well as this:

        …which means it is the best handgun sight I’ve ever shot.

  • PGConley

    Wouldn’t it stop being a revolver technically? And amazing what people can do when they puf their mind to it.

    • Jean Luc Picard

      Technically it stays a revolver but it’s more something in the vein of the Dardick revolver for those who knows what it is.
      The Dardick revolver instead of using a tube magazine and also normal cartridge cases used Triangular Cartridges stored in a magazine who are loaded in a revolver drum to bring a round into firing position and eject. It was quite an innovative weapon that never found its public as it’s a rare weapon

      • PGConley

        Fair enough, I should have watched the video before I commented, but yeah that’s entirely accurate. From the description in the article it seems like just pretty much does automatic actions through the cylinder with out it doing anything, but clearly from the video it just seems like it kinda almost has an extended magazine with the cylinder. Very Cool.

        • jimmarch

          Once the cylinder runs dry and an empty chamber passes in front of the magazine there’s a distinct “clunk” sound as the top round of the mag slams into the cylinder. This happens on cocking, not firing, so it’s very clear.

          That means if I’m carrying it with five in the cylinder and the short 2rd carry mag inserted for a total of 7 shots, the gun tells me very clearly when I’m down to my last two shots. I can fire and cock it one more time, and now it has a live round under the hammer and one in the cylinder bore ahead of the mag.

          I can then, if I want, pull the 2rd mag and slap a 9rd in…for a new total capacity of 11.

          OR, if am in a “bad place” and smell trouble, I can draw, pull out the 2rd mag, shake two rounds out of the mag well, pocket them, slap a 9rd mag in and reholster.

          I now have 14 on tap, with no reload.

          Another weird option:

          Start with 14, 9+5, run it completely dry, and on reload with another 9rd mag drop a single round down the mag well first. That gives me a 10rd reload instead of 9. Doesn’t take much extra time. And that means with 24 rounds on tap with one reload I could shoot an entire SASS stage with one gun at competitive speeds…if they’d let me of course.

          I once added up all the SASS rules Maurice violates. Best I can come up with is: “all of ’em”.

      • jimmarch

        The cylinder in Maurice is utterly conventional. It started as a Bowen cylinder blank (cost me $270) and is chambered in 9mmPara. There’s some minor tweaking involved: the rear of each cylinder bore is chamfered for easier shell insertion from the rear, and the shell depth is set so that the backs of each shell are dead flat with the rear of the cylinder.

        Ponder that last…each time I cock it there’s a shell in the mag that is having it’s nose poked into the rear of the cylinder, so it can’t be too “bumpy” there! And the cocking stroke is admitedly a bit “funky”…not too bad but…there’s some odd scraping going on.

        If I was dumb enough to do this to a DA revolver the DA trigger feel would be ghastly.

    • Michel_T

      Add a few more rounds to the magazine tube, and you’ve got a nice little carbine!

  • Tinkerer

    Hmmm…. wouldn’t it be nice if the ejected spent casing would cock back the hammer upon ejection?

    • jimmarch

      Yeah, well that doesn’t work BUT in theory I’ve got enough muzzle gas on tap to rig an auto-cocker. Problem is, with no separate sear and disconnector we’ve got a Hughes Amendment problem so…no. 🙂

      • BOBTAIL101

        In one of the palladin press books from the 70’s there was a sigle action ruger in .30 carabine that had been modifified with a mi carabine piston system on the end of the barrel to fire full auto. apparently used in a california murder

        • jimmarch

          Yeah, I can see how it could be done. Tap the gas trap, run the tube into a line that runs parallel to the barrel, run a capped outer tube over the inner tube with the outer linking back to the hammer. On firing the outer tube is slammed back to cock it. Adjust gas pressure and bingo. Hold the trigger back it’ll go full rock’n’roll, release and it stops.

          You could even rig a gas dump switch somewhere near the muzzle that disables full-auto.

          If they ever revoke the Hughes Amendment I’ll consider doing the paperwork, if they repeal NFA34 hell yeah. But it’s not something I would find necessary.

          • BOBTAIL101

            As I remember the piston tapped the cylinder pin which recocked the hammer By the way your system applied to the rossi lever action revolver rifle with the a skeleton stock would be better than steam punk

          • jimmarch

            Tapped the cylinder pin…wha…OH, OK, he modified the cylinder pin so that it could travel deeper in. Hrm. A fellow sick puppy traveler ‘cept he didn’t care about legalities :).

            Not really a good design though because the pin would wear and make the cylinder sloppy, ruining accuracy. My method would look weirder (not that THAT stops me much) but it would have at least some advantages.

          • BOBTAIL101

            Sorry I was off to bed here in france.. Auto revolvers now about 2 years ago our gun mag CIBLES published a series of patents on all the auto revolver patents out there. .It ran for 3 months but I can’t remember which months or year. I do remember the russians as usual had some good (crazy) ideas .Maybe somebody else from france could chip in and give the patent numbers

  • Isaac FluffyWolf Rader

    I saw a comment from the guy himself on forgottenweapons where he linked to this. Fun stuff

  • Jean Luc Picard

    I saw this already I’m surprised that it only reaches TFB this year !
    I knew this man mainly for doing a revolver that self eject cases which is a cool thing IMO

    check this out 🙂

    • Captian Picard, Unlike the Enterprise, we are unable to warp around the entire internet galaxy. We are not “Q’s”


      • M.M.D.C.

        Well done!

      • Jean Luc Picard

        Heh, nice joke here :p

    • jimmarch

      That was a test of the gas-ejection system while the gun was still a 357Magnum. SAME GUN…but now it’s a 9mmPara.

      Care to guess why?

      Because 357 shells were too fat to be slipped past the pawl through the new hole in the left side of the recoil shield.

      In the 357-gas-eject phase of the project I was running the gas line as you see here because I still needed the manual ejector rod to get the last shell out. Once I had magazine feeding working the manual ejector wasn’t needed and that let me run the gas line much cleaner through the point in the frame where the ejector rod used to be. See, once the cylinder and magazine are dry, the gun ends up with hammer on empty and the magazine’s follower poking forward to tie the gun up. So when you try and cock it and can’t, OK, time to swap mags. And then when you do that and cock it, you put a live round under the hammer and the empty will be in the regular auto-eject location.

      The muzzle gasses on firing do NOT eject the firing shell. They eject the previously fired shell in the cycle.

      Something else…I was very, very surprised when I converted the gun to 9mmPara because shells were gas-ejecting MUCH faster than they did in either 38Spl or even 357Magnum. It turns out the tapered short 9mm shells come flying the hell outta there HARD, enough to sting my right cheek the first time I tried it. 357 had been bouncing gently off my goatee! So I went back to the shop, drilled a hole in the hammer from the right side and soldered in a brass shell deflector pin, set far enough back with the hammer down that the 9mm shells clear the cylinder bore just before bouncing off the pin and flying back past my head about 2ft to the right at full arm extension.

      • Jean Luc Picard

        I do care technical aspects of custom weapons is always interesting mostly that I often care about the mechanics in such creations 🙂

        • jimmarch

          I have had one conversation so far with an old aircrew guy who worked on the US M39 that was based off the captured Mauser prototype. He said the feed reliability was very good, mainly because the feed path into the back of the cylinder was dead straight. That’s been my experience as well, and probably the most interesting thing I’ve learned from all this. This thing doesn’t care about the shape of the bullet or the overall length, at all. It’ll feed empty shells just fine and I plan to brew up some wadcutters at a shorter OAL to get 10 into each of the long mags.

          The US seems to have abandoned the design mainly so they could get higher rates of fire out of multi-barrel electric Gatling guns? Which in turn share the feed path characteristics of the Mauser MG 213 and Maurice…

  • Nathaniel F.

    Firstly, this is very cool, and very inventive.

    I am not very familiar with California handgun law. Wouldn’t a “single action only” semiautomatic handgun where the hammer had to be re-cocked between every shot fit this niche even better?

    • jimmarch

      Not exactly, because you’d still have a 10rd mag limit.

      “Maurice” here has magazines of either 2rd (short, used to top off 5 in the cylinder) or 9rd (mainly used as reloads but CAN top off 5 in the cylinder) for up to 14rd capacity. That’s because there’s two different ammo feeding devices involved, the cylinder and the magazine, and it auto-switches between them.


      I think I can get 10rds into the foot-long mags by handloading some Penn Bullets 100gr double ended wadcutters (available in .356) in 9mm cases. Maurice has a dead straight feed path and doesn’t care about OAL or nose shape – it’ll feed empty shells just fine.

      In case anybody is wondering: it’s “Maurice” because some people call it The Space Cowboy:

      • wetcorps

        Man, now that I know the origin of the name I love it even more. You truly are a mad genius.
        I’ve been aware of the existence of Maurice for some times now but was never able to find much data about it. Is there a post somewhere where you do a thorough presentation of how it works with more pictures? And better videos? If not, maybe you could do an article on TFB 🙂

        • jimmarch

          I’ve had a crazy year including a sudden move to Alabama and marriage that was a “wow, didn’t see THAT coming!” kind of thing. In a good way mind you. I finished Maurice just before leaving Tucson in Jan. of 2013. Main development after that has been improved latches for the 9rd mags and a dual-mag carrier in mixed kydex/leather.

          So…now things are finally settling down a bit, and I have access to another machine shop. I want to improve a few things and then race it – Steel Challenge Revolver class, ICORE, something like that. Maybe a SASS stage here or there if they’ll let me just for fun :). With video – I also have a Looxcie2 head-mounted camera that should work great.

          Planned tweaks involve a billet funelled mag well and a gas trap that doubles as a comp. The current mag well out of copper pipe is…marginal at best, weakest part of the whole thing. A better upper-stage loading gate would be nice too.

          • wetcorps

            Well keep us updated if you can 🙂

    • Cymond

      There is also a special exception in CA state law for single action revolvers. See, there’ a thing called the ‘safe handgun list’. It’s a “white list” of all handguns approved for sale in California. Guns can stay on the list as long as the gun manufacturer pays $200 every year for every model. Unfortunately, guns go off the list if the design is modified in any significant way, and the only way to get back on the list is to retested. And more unfortunately, a gun can only be added to the list if it meets the current criteria, and they keep increasing the requirements to get on the list. This is the reason you can buy a Gen 3 Glock but not a Gen 4, or a FNH FNP-9 but not a FNW-9. At this point, the new “microstamping” requirement essentially guarantees that no new handguns will be added to the list. It’s only a matter of time until the older gun models are altered (and therefore removed) or discontinued.

      However, single-action revolvers are exempt from all of this insanity as long as the meet so very easy requirements about barrel length and overall length. (And there’s no law against modifying them after you own them.)
      Hence, some people who want a double-action revolver that is not on the list of approved guns will have a gunsmith modify the revolver to single-action before it is sold, and then modify it back afterwards.

  • 101nomad

    I would not buy it, be afraid to so much as shoot it.

    • jimmarch

      Well here’s the thing on safety…

      The cylinder is a Bowen chromoly blank that can be safely chambered in 41Magnum. I’m running it in 9mmPara. It ain’t gonna blow up…no way, no how.

      The frame is weakened just a tad from the new hole in the rear where the magazine inserts rounds, just left of the hammer. Sure. But that frame (Ruger New Vaquero) is chambered by Ruger in 357, 44Spl and 45LC. It has also been successfully used as a six-shot 41Magnum and a five-shot 44Magnum (by Hamilton Bowen) with no problems. So even if I weakened it by maybe 20%, I’m running it in 9mmPara.

      Right…so it ain’t gonna blow up.

      Let’s say the shell deflector pin falls out and it spits a shell back at me under gas pressure. Well I ran it that way for a cylinderful to test the initial conversion to 9mm. The shells came back with more force than expected but it was just a sting to the cheek, no injury at all. No big deal there.

      Say the mag falls out. OK, live round falls out the back of the gun. Not what I’d call a disaster.

      The Ruger transfer bar ignition is still there, so it’s still drop-safe.

      I don’t think I’ve done anything unsafe here.


      I had some interesting failures testing gas-ejection in 357Mag. The first gas-trap I tried just after the muzzle was a beautiful brass creation. Looked great. Worked great too, in 38Spl. First shot of 357 blew it ten feet downrange. Whoops :). No injury to me or the gun though, other than “oh well, back to the drawing board”…

      • 101nomad

        No, sorry, it is a work of genius, really, I meant I would be afraid to shoot it, period. Good luck. Having choices is wonderful.

  • jamezb

    Good Grief man, I love crazy innovative frankenguns!

  • Jeff

    Even in the absence of California compliance laws, does anyone else think an auto-ejecting revolver pretty cool to watch?

    • jimmarch

      You should see the looks I get at ranges.

      I built this after I scored my CCW permit in Arizona. Then early in 2013 I moved to Alabama, scored CCW here but there’s no training required. Eventually I’m going to end up moving to a state where training is required…and a class…and some poor CCW instructor is gonna get a true WTF moment…

      Oh yeah, almost forgot. At one point I Emailed this video to the Texas Department of Public Safety and asked if qualifying with this would count as doing so with a revolver or auto, back before they changed the law on this (doesn’t matter anymore).

      They had no idea.


      • gunslinger

        South Carolina has a class instruction and range testing for CCW

        • jimmarch

          Well my wife and I will likely be moving somewhere in the South a year or two from now so we’ll see. If I have the cash together anytime soon I’ll do an FL for more reciprocity.

  • jimmarch

    For the record, this was NOT an attempt to beat the Cali 10rd mag limit. It DOES do that mind you – five in the cylinder plus 9 in the cylinder equals 14, with auto-switchover between the two feed methods. But I built this in Tucson AZ, not California. I have noted that it’s a potential dodge from any 10rd mag limits.

    In theory, the Ruger 8-shot large-frame 327 SA Blackhawk could be reamed bigger to 9mmPara 8-shot. I think there’d be enough beef in there to do it. That would give you 10+7 in a state with 10rd mag limits.

    The reason you have to downgrade the cylinder by one is you want the hammer down on empty when you start. Can you see why? Because this system ejects the empty shell that fired previously, not the one under the hammer that’s firing. So on the first shot, you cock it and the empty chamber goes to the autoeject position and you don’t gas-eject a live round! I *am* using that first gas pulse though, because if the hinged upper half of the loading gate isn’t down yet after draw, the first “dry” gas pulse flips it down. Why have an upper half of the loading gate at all? To retain shot #5 in the cylinder while the gun is holstered if I jostle it!

    Other notes: this feed cycle has been used before, but never in a personal weapon to my knowledge. Late in WW2 the Nazis had a prototype 20mm autocannon with a five-shot cylinder and one barrel, and it worked like this:

    There are some differences of course: I’m using a spring-loaded tubular mag with single-stage insertion, the Nazis used a two-stage mechanical “rammer” to strip rounds off the top of a conventional magazine. They also used mechanical extraction instead of the direct-gas setup Maurice uses. But those are quibbles.

    I found out about the Mauser MG 213 and the clones the US and others made of it post-war (such as the Pontiac M39 used in the F86 Sabrejet) halfway through my build while still testing the ejection cycle in 357.

  • Joey Szabo

    I’m just glad to know that in AMERICA(F$#% YEAH) where there is a will there is a way. Nice job.

    • jimmarch


      Much credit goes to Xerocraft in Tucson, a “makerspace/hackerspace” that gave me lots of quality time with low prices on a 1956 Logan 11″ lathe and a Bridgeport-type mill. I had to watch scads of youtube videos and re-learn what I’d forgotten from high school metalshop 30 years ago.

      Hackerspaces are a really cool movement.

      I didn’t need to use their 3D printer but it was awesome watching it run…a lot like seeing a primitive car in 1880 or so and knowing it’s not that practical now but it’s clearly going to change the world…

      • noob

        I love the look of it as well. Has the word “steampunk” been said in this discussion yet? I mean it as the highest compliment.

        • jimmarch

          Sigh. I know. As God is my witness this is a case of “accidental Steampunk”. I tried to upgrade an 1873 design with, in part, hardware store bits…and…at some point it was like “ah crap, might as well shop for brass goggles”…

          SASS has been joking around about a possible “steampunk open class” for years… Maurice might end up being the first one. With my luck I’ll end up racing guys with leverguns rigged with a rotary multi-magazine underbarrel setup…which would be really cool on a Rossi “Ranch Hand”, come to think…

          • noob

            If you decide to make a long arm with a poly-choke, customized trigger and at least one sagia part please, for the undying love of nerds everywhere, call it “Vera”.

            Sir, your taste in guns is awesome. Hats on the other hand…

  • Giolli Joker

    Now it needs a bit more gas to be trapped to push back the hammer after each shot… 🙂
    I love the ingenuity of the design, it would deserve a more practical/professional (=less steampunk) look… for mass production! 😀
    Great movie gun, BTW!

    (with 12″ barrel and fixed foot long magazine it could be UK legal…)

    • jimmarch

      Fixed mag won’t work. Unless I could rear-load it I guess?

      Gas-cocking the hammer would be problematic, legally speaking. No disconnector. Bra-a-a-a-a-tatat…

      I have access to another machine shop now and will be doing a billet mag well. That will help. And now that I know there’s more than enough gas pressure for 9mm ejection I’m going to rebuild the gas trap to be a comp as well.

      It’s looking like something Gecko45’s great grandfather would have packed.

  • AD

    Very cool! I keep thinking this would work really well with a stock that automatically feeds straight into the cylinder. And since the barrel is removable like a Dan Wesson, I reckon it’s conceptually possible to convert it to a rifle and avoid having a SBR.

    Alternatively, have you considered reversing the magazine so it lies along the barrel and feeds backwards? Of course there’s a problem with heat there, I dunno how hard it would be to put some ceramic or something between the barrel and magazine for insulation in that case.

    • jimmarch

      The rounds have to enter the cylinder from the rear, pointy end first. So…coming in from the front would be tricky. The stainless steel tubes I use for mag bodies can be had up to 3ft long and with a tube bender, spiral maybe?

      The other option is to rig a shell rammer on the hammer so that as it drops it strips a round of the top of a Glock mag or the like that sticks out the side somehow. Tricky to pull off and I’d need a 30lb mainspring (?) or so to maintain ignition reliability. I would also need an ultra-short altered mag for carry in a holster and then switch to full mags on reload, unless the mags came in from almost straight up, but that would limit field of view when shooting…


      • AD

        Of course, I forgot to consider the difficulty in getting the round to stay at the back of the cylinder and stop the next round from getting stuck halfway if trying to devise a front-feeding system. I assume the cylinder has to headspace at the case mouth to hold the round in place and stop the next round from trying to push it’s way in.

        • jimmarch

          Right, it headspaces on the rim just like a factory Ruger 9mm or 45ACP cylinder.

    • jimmarch

      On a rifle conversion I could do a skeleton stock that holds multiple mags ready to go…”I heard you like magazines so I made a magazine for your magazines…”

  • gunslinger


    wonder what a production model would run. a “powerball dream” here..

    • jimmarch

      Well DA wouldn’t work well. Crazy horrible trigger feel. As it is the cocking stroke feel is “way funky” (scrapebumpchunk) but tolerable.

      See my other post about converting it to run off of Glock mags. That would be cool. 30rd sticking out the side like a grease gun…hell yeah.

    • jimmarch

      Oh, by the way: the best way to make more would be to special-order an Italian SAA-type as a pure 9mmPara with a true 9mm .355″ barrel and no ejector hardware and the front sight mounted 1/2″ or so back from the end of the barrel. At that point the modding process wouldn’t be bad at all…thread the end of the barrel to add a gas trap, run the gas line, split the loading gate, new hole on the left, bolt a mag well in, make some mags, done.

      It would be less work than doing a full cartridge conversion to an 1858 Remmie type cap’n’ball with ejector hardware and true loading gate. And since you wouldn’t be changing the caliber, cylinder or barrel you wouldn’t need a handgun manufacturing license, just a gunsmithing FFL would do.

    • jimmarch

      Well it would be easy to bolt on a long support for the mags that permanently stretched the gun to make it work in the English “handgun” length limits (eliminating concealability).

  • WOP 2

    Jim–Kinda looks like my recliner’s mechanism, which I had to repair last week. If it looks stupid, but it works, its not stupid. I’m real partial to 1911’s, but I’d love to shoot your auto revolver. Looks like you enjoyed yourself to no end in making it.

    • jimmarch

      I actually spent a lot more time perfecting the sights.

      From 2005, here’s the first custom sight setup:

      Novak front, rear stock sight channel milled out to match by a gunsmith in the Seattle area. This was a lot better than stock but it didn’t “feel right”. (I did the SuperBlackhawk hammer swap even earlier.)

      Then I read everything Tim Sheehan had written about target-focus hex-aperture sights and I whipped up the “Goshdarn Hacksite Mk1”:

      Brass tube with a chopped-off section of socket in the rear, post front with fiber core. This worked “way better” but there was a major problem on draw from that sight, and the red front didn’t feel right. I took the fiber core out, that helped but…still had a snag issue from hell. Cured that in short order:

      Better, lots better. Greasy smooth on draw and the front is now dead black through being in shadow. Tim’s real Hexsite post front sight post gets a “zero glinting” effect by coating steel cores with high-tech polymer similar to what a Glock is made out of – highly wear resistent, no glinting ever. Lacking that I used shadow instead.

      BUT the brass tube proved fragile and warped in the holster. After various failures in steel tubes that I’d rather not talk about I settled on what I have now and can’t discuss too much. Enough said that once I had the sights sorted it was time to work on the firepower :).

    For another historical reference see:

    Rollin White’s “Improved Repeating Fire-Arm” of 1855. A revolver where the cylinder is fed extra (percussion) cartridges from a fixed side-mounted magazine when the hammer is cocked.

    And the patent:

    I would also like to add a personal thanks to Jim for being creative, open and talkative with regards to his highly interesting design. I fall squarely into the category of “hair-brained” design dreamer/enthusiast myself and it’s always encouraging to see someone take their vision all the way from the drawing board to the firing range!

      I think if there’s one thing other gun tinkerers (pro and amateur) can learn from “Maurice”, it has to do with the inherent reliability of straight-line ammo feeding. I hope to do videos this year where I shoot it in competition, under stress, with full wadcutter 9mm ammo…something basically impossible in most autoloaders.

      The Boberg pistols are kind of doing straight feeding too:

      …although it turns out yanking rounds backwards at slide speed induces other issues(!).

      Now ponder this. A huge amount of possible gun-tinkering has been shut down with the near-total ban on full auto, esp. now that the Hughes Amendment prevents any newly made autos in private hands. Well in order to make a full-auto gun work well you also have to work out reliability and recoil-control issues and private research in those areas by anybody outside of mega-corporations like Freedom Group are just not happening.

      And if developer/hacker/tinkerer history tells us anything, it’s the little guys that innovate the most – doesn’t matter if it’s cars, guns, motorcycles, computers, whatever.

      This is the biggest flaw in the Hughes Amendment.

    Remember the street sweeper shotgun? I need to see one that works like this!

    On those last two shots your hands were awfully close to the cylinder gap.

    Great job nothing to be embarrassed about . Every thing has to be fined tuned before production!
