GSG Unveils .410/.45 LC Derringer

German Sport Guns GmbH has introduced a combination .410 bore/.45 Long Colt derringer for personal defense. All4Shooters has the story:

The new .22 Long Rifle pistol lines and the 9x19mm caliber semiautomatic version of the legendary Mp40 sub-machinegun design are not the only new products showcased by the GSG – German Sport Guns company at the 2015 edition of the IWA Outdoor Classics expo in Nuremberg − nor they probably were the most interesting after all.

As a matter of fact, the company also showcased the first prototype of its compact, double-barrel, two-shots defense pistol, dubbed the GSG-P.D.R.(“Personal Defense and Rescue“) that should go in production and on sale later this year or early on in 2016, and was conceived as an “all-rounder” defensive piece against home invasions, carjackings, assaults and aggressions in the public way, or as a protective backup for backpackers and outdoorsmen when out in the wild.

Offering a solid, modern and lightweight metal and polymer construction, the German Sport Guns GSG-P.D.R. double-barrel pistol breaks open for reloading and offers two over-and-under barrels which can use .410 gauge shotshells or .45 Long Colt ammunition; the GSG-P.D.R. also features a frame-mounted manual safety on the left side, ad easy thumb reach, as well as a cross-button located on the rear portion of the trigger guard that can be activated when the trigger is pulled halfway to select which of the two barrels will fire first; being the GSG-P.D.R. a double action only design with a long trigger travel, this can be done in total safety.

It’s not clear what the attraction of a firearm like this is versus a more conventional compact or subcompact semiautomatic firearm. As with all firearms like this, price will play a key role in its success or failure.

    I don’t get it. For ccw it looks bigger than most sub compact 40s and 45s. For a survival gun a takedown 22 would be more useful.

  • Anon

    Oh boy, a new snake charmer.

  • Dracon1201

    Unfortunately can’t really see a good place for this. Maybe a throw away car gun or something, but carry? I don’t think so.

  • Franciscomv

    I’m not sure who’d buy this. There are far better options out there, I mean even if I did want a derringer in .410/.45 Colt for some reason, Bond Arms makes much nicer ones.

    • lucusloc

      Why would you get a $500 two shot derringer when you could get a cheaper pistol that carries significantly more rounds in roughly the same space?

      • Franciscomv

        I wouldn’t get a derringer based on my actual needs, I’m happy with my 3″ SP101.

        If I did buy one it would be just for fun (although there are plenty of guns higher up on my list), and it wouldn’t be this one.

  • Cornelius Carroll

    The only way I see this working is if it’s super cheap. Like… $100. Even then, it would basically serve the “better than nothing” home defense market which I’d imagine does exist.

    • Swarf

      If they hit that price point (they won’t. Not even close) I would get one for the car.

      Otherwise, that thing looks bigger than most pocket nines, so I don’t see the point. At all.

      • Sulaco

        Well as a backpacker I can kind of see it. Different shot for small game on the trail and .45LC for bear or two legged hostile types.

        • allannon

          I wouldn’t risk just 2 shots with a bear. It’s probably about as like to just make it mad. :p

          If I were planning on taking game and defense I’d carry on-body a 9mm-.45 for defense, and a .22lr/mag pocket revolver for rabbits or whatnot.

          If I were semi-serious about the hunting, a lightened and TD-converted H&R or something similar. :p

          • Sulaco

            Some good choices but I was more leaning towards the multi use rounds and very light basic pistol. That’s a lot of poundage you are listing there along with ammo, holsters and assorted gear to go on your back. I was more thinking of the ultimate basic in carry for back woods camping if you must have one at all….

          • allannon

            Sure, but you’d end up with useful gear.

            .410 pistols start reaching useless levels of spread at less than 10ft, and usually have pretty low penetration (even by small game standards) at those ranges.

            They’re fun, but I wouldn’t add one to my pack; I’d rather eat the weight for a SS .410 shotty or a .22 rifle (better, .22 mag or even .17hmr…just a bit more oomph), and a pocket auto. Then you have a solid defense gun and a solid light-game longarm.

            If I wanted to shave ounces I’d carry a medium-length .22mag revolver. (I don’t know of a .17HMR revolver, or I might consider it for the mix.)

            My pack’s about half milsurp because I’m actually cheaper than I am lazy, and milsurp gear is rarely the ultralighter’s choice.

            Damnit…now I want to experiment with lightening my old SS 20ga. Like I don’t have enough pointless projects in the garage. :p

          • iksnilol

            Chop the barrel and stock to minimum legal length (possibly further if you SBS it). Turn down the barrel. to minimum safe specs (remember that barrels are tapered for a reason). Hollow out the stock, possibly skeletonize it. Make a lighter handguard that isn’t as big or heavy.

            Though I warn you, that thing wouldn’t be fun to shoot. Also be warned with a thin barrel fixing dents and bulges is hard because you don’t have the metal to work with.

  • iksnilol

    Make it… make it 12 gauge. That way I don’t have to cut down a O/U shotgun.

    • Coming soon to TFB TV: Watch Patrick break both of his wrists!

      • iksnilol

        What? You shoot it once with one hand so you don’t break the other wrist. Might smack up your face but it is better than breaking both wrists.

  • Vhyrus

    If it is super cheap I would put one in a simple bug out bag or possibly under the spare tire of the car.

  • Imagine

    I will buy one for snakes when I’m out fishing and don’t want to be burdened with a large pistol and snake shot. It’s GSG and polymer, so I can’t imagine a street price over $200.

  • HM

    It’s looks a little on the large side, but at sub $200 it would be useful thrown into a vest pocket while doing field work.

  • BryanS

    Three of the items in that photo are a good idea, and one is a gun.

  • Sianmink

    Since that looks about the same size as an XDs45 I gotta ask,why?

    • Tim Pearce

      Well, from the wording, it seems like that could be done with the gun empty and you could leave it set to whatever order you chose. Yes, it does seem strange to include a trigger pull in that process, and violates one of the Cardinal Rules of Gun Safety.

    • Andrew

      You would do that unloaded.

  • Nicholas Chen

    I like it for the aesthetics. It looks like a prop from Blade Runner.

    • Phillip Cooper

      If the price was attractive, would be a fun range toy, with a possible use as a hunting sidearm (not for Bambi- I’m kinda psycho against snakes, but then we have quite a variety here that will kill you fast)

  • Rick

    will we ever see it in CA? probably not

  • Alex Nicolin

    Bring on the 40x53mm/14.5x114mm derringer!

  • Captain Obvious

    In 30 years someone will write an article on TFB about obscure pistols brought out in the mid twenty-teens. This will be mentioned as something in the “what were they thinking?” column.

    • Cal S.

      No, my friend. That honor belongs to Heizer Defense and their stellar engineer who said “Hey! Let’s build a pocket AK for the price of a real one!”…

  • jamezb

    I hate to be the one to break it to you folks, but all your arguments against this pistol sound just like the arguments used by anti-gunners.. What good is it for __________ compared to _______? Why do you need 30 round magazines to hunt deer or shoot targets? Why do you need pistols when you can shoot your double barrel shotgun through the door? Why do you need bayonet lugs and the shoulder thingy that goes up?
    And that is all the reason this pistol needs to exist.
    Don’t like it? Then FOR HEAVENS SAKE DON’T BUY ONE.
    But don’t hate on the guy who does, thank him for exercising his rights.

    • BryanS

      Or, try educating them so they make a sensible choice next time. there are people out there who think derringers are good ideas. Great if you want to screw around… not great for anything meaningful.

      • jamezb

        You convinced me. Lets ban them. And AR15’s too. Once we re-educate you, you will see we were right and you were wrong.. AR’s have no legit use.

        Listen to yourself.

        • BryanS

          No, go to a gun show some time, and see the amount of first time shooters, predominately women, who get sold on this idea of a derringer or air weight frame magnum revolver.

          Which, will probably be shot one time, disliked, and we lose another possible lifelong shooter.

          technology has progressed since the 1800s… and made the derringer very, very obsolete. Sure, buy one and screw around with it. Pay $900 for that titanium one in 7.62×39. But dont let this or something stupid like a Taurus judge be the first go to. Hell, even a Highpoint C9 is a better option.

          Di I say ban it? Did i say to take it off the market? No. Its just a stupid idea.

      • jamezb

        I have long guns, Short guns, Shotguns, Pistols, Revolvers, Bolt guns, Semi’s, Pumps, Target guns, Plinking guns, Expensive guns, and cheap guns.
        I bought most of them just to screw around.
        Because I have the right to own this diverse variety of guns.
        Because I can.
        My .41 Remington derringer is pretty useless too.
        They haven’t made the shells in decades, and wouldn’t you know it I don’t have a single round, much less two.
        From what I understand, they are less than formidable..
        And hey…It’s no GLOCK.
        I guess I should turn it in…ought to be a law against something that small anyway, huh?

  • Mister Thomas

    Definitely interested in seeing this come to market

  • dan citizen

    This is just like the Taurus judge…
    Many people will wonder “why” and “what for” and meanwhile it will fly off the shelves.

    On a ranch I managed we had one of those little leonad o/u derringers in .22 and 410/45 that was always kicking around. We used it for all sorts of tasks, euthanizing livestock, shooting snakes, scaring coyotes off, etc.

    This thing looks handy and fun, and for all the haters saying “but my _____ pistol is that size” how many compact pistols shoot either 45 LC or .410, let alone both?

  • nobody

    Neat, if it has a 4″ barrel it should get about 15″ of penetration with the Federal 4 pellet 00 buckshot (~20″ is normal from the 2.5″ barrel Taurus Judge Public Defender if I remember correctly, see shootingthebulls’ tests on youtube). Considering the grip is hollow, is the grip removable? If you can remove it you could cut it down to a one finger grip to make it a bit more concealable without having to worry about ruining the gun if you mess up. They could have skipped the safety and barrel selector though. I wonder how much it’s going to cost.

    • iksnilol

      I wouldn’t skip a safety, especially on a derringer or other gun that is meant to be concealed/carried on your person.

      • nobody

        …or you could just use a holster that covers the trigger.

        • iksnilol

          You really like messing with Murphy, don’t you?

          • nobody

            If it was an actual problem then revolvers would have had safeties added decades ago.

          • iksnilol

            I don’t know, they carried revolvers with one chamber empty in the old days as a form of safety. That and they were single action which obviously won’t fire if the hammer isn’t cocked.

  • DIR911911 .

    that’s a whole lot of gun for only two shots , if that guy’s hand is anywhere near the size of mine that means it’s about the same size as my taurus pt145.

  • PeterK

    Huh. Well if it’s not complete crap, I like the idea. Drop safe?

  • Marcus D.

    Total fail.

  • Part of the attraction of strange pistols like this is the gun laws in Blue States and other countries. When i was younger there was a push to ban handguns with six rounds or more – making most revolvers illegal. In some South American countries you can own a gun if it’s not chambered in a round police or military use. Maybe their thinking of the future
