9×18 Makarov Glock 42?

The guys at Lone Wolf have come out with a conversion barrel that will allow you to shoot 9×18 Makarov out of a Glock 42! I had dismissed the Glock 42 since it shoots .380 but now that it can shoot 9×18 Makarov I am intrigued. The photo above a little misleading as it shows a threaded barrel but on their website they only have a stock length barrel. I am sure in due time they will have a threaded version. Now I am tempted to get a Glock 42 . . . for the Mrs.  Yes for the Mrs. LOL

The lone wolf barrel retails for $159.95. Click here for more info.

    Why would you dismiss a co conceal carry gun that fires a perfectly capable round? hitting someone with a .380 is much better than leaving your 45 at home

    • Steve

      Perhaps a better question – why spend ~$625 to buy and convert a Glock over a just buying a $250-300 Makarov? The guns are damn-near bombproof.

      • Twilight sparkle

        Or better yet a cz82

        • ostiariusalpha

          Unlike the Makarov or CZ, this is a locked breech pistol. Technically, that would make it a softer shooting gun, so it would be interesting to have a comparison of the three.

      • Harry’s Holsters

        I love conversion but this seems like a solution without a problem.

      • Matthew Groom

        I want one because I already have a Makarov. I had a CZ82, but it wasn’t machined right back in the 80’s, and never worked.

      • Bob

        My G42 cost me $320 out the door

    • M-cameron

      Let’s be real, If your lazy ass is going to leave a 45 at home……your lazy ass is also going to leave a .380 at home.

      • Twilight sparkle

        Not necessarily, a lot of people over estimate the size of the handgun they can comfortably and practically conceal carry all day. The glock 42 is a good size for most people. Women especially have to be more mindful of the size of a handgun because of the clothing styling for women is generally a lot more restrictive than for men.

      • Matthew Groom

        The bolsters on my car’s seats make it impossible to carry in any way other than AIWB/Mexican Carry. This also limits the size of the gun I can carry, since I live in FL, and wearing two shirts to cover up a handgun is impractical when it’s 97-Degrees and 80% humidity. I carry a .380 SIG 232 most of the time because it’s light and compact, but still of a usable size, and doesn’t poke me in the thigh when I’m sitting in the car. Yes, there are several 9x19mm’s and other designs which would serve this role, but I don’t own one of those, and I’m not going to spend $400+ just so people on the internet will nod approvingly. I carry a .380. If it doesn’t work well enough, I also carry a Spyderco.

      • Bill

        Not really. I wouldn’t carry a .380 as a primary, but after carrying a full-size pistol at work, a lighter, more compact pistol makes more sense of duty in soft close.

    • Cal S.

      Why did you leave your .45 at home?

      That statement has always seemed non sequitur to me, even though I get the gist behind it…

      • Twilight sparkle

        Because I can’t practically carry a 45, and now that I switched to a camaro I’m stuck with a compartment the size of a bersa Thunder, so now I have two .380s that go with me.

        • Cal S.

          Then why did you say that like it was an alternative? ;P

          I’m just taking a stab at the saying, not you, my friend. When I first heard it it was “A .22lr in the hand is better than a .45acp in the bedroom drawer.” All I could think about is why they had a .22lr in their hand if they had a perfectly serviceable .45acp in their drawer?

          • Twilight sparkle

            It’s meant for people who scoff at smaller guns, in my experience a lot of less experienced and usually male shooters will favor a larger gun than they really want to carry because they see something smaller than 9mm or sometimes 40s&w as being too weak for them and they’ll later find out that they won’t actually carry the larger pistol.

            This was happening a lot with the Taurus pt111 in my area when people were trying to get one gun to fill two roles. What they really should have done was save up and get two guns, one for conceal carry and one for fun at the range.

  • It’s an interesting choice, and choice is good. However I’m not sure what real benefit it offers, as 9×18 now is comparable in cost to .380.

    Meanwhile in terms of power, they are both nearly identical.

    Per Underwood:

    .380+p 90gr XTP: 1200fps/288ft/lbs
    9×18+p 95gr XTP: 1150fps/279ft/lbs.

    Personally I would have loved to see a version in .32 NAA. The improved sectional density w/ 85gr XTP’s consistently hit 12″+ penetration in Brassfetcher’s testing.

    • Matthew Groom

      I question the veracity of Underwood’s numbers here. Their stuff is either wildly over pressure, or they’re using much longer barrels. My IJ-70 barrel is about 1/10 of an inch longer than my SIG 232 barrel, and I can’t get anywhere near those numbers using SAAMI or CIP pressure limits, and my 9×18 loads are VERY hot.

      • Evan

        Underwood is known for hot and heavy loads. They’re one of few companies who make original-spec 10mm loadings for instance, not the downloaded “FBI Load” like most other manufacturers.

        Another example, they also make a 1000fps 50 gr. .32auto loading.

        • iksnilol

          that isn’t impressive if it is .32 acp. That’s standard velocity with 30% less weight.

          • Evan

            Right. I was just explaining they’re known for doing odd loadings that don’t necessarily fit the market.

          • If you want impressive, they have a .357 Sig load that does over 1500 fps out of a 4″ G32 barrel. That’s what got me hooked on Underwood.

          • iksnilol

            What bullet weight?

            Again, speed isn’t everything. RE: .22 LoundesplittenEargeboomer.

          • Sorry, that’s with a 125gr.

          • iksnilol

            That’s slightly faster than usual but not so much as to make people go “wooow!”.

          • I’d say it is, given pretty much all of the other options for .357 Sig are doing 1300-1350 out of a 4″ barrel.

      • John Yossarian

        To my satisfaction, vetting by multiple sources have proven Underwood’s numbers are sincere. However, you are correct that barrel length should be posted for all velocity numbers – Otherwise, they are next to useless.

      • Underwood typically understates their velocity figures by 30-50 ft/s from testing I’ve seen. I’ve seen tests of their .380 +p hitting 1150 ft/s out of a 2.5″ Kahr P380, so I don’y doubt it their numbers for a moment.

    • Jeff Smith

      Well said, though the specs listed are for Underwood’s ammo are +P variants of .380 and (I’m guessing) 9mm Makarovr are non-standardized calibers. Many handguns specify that shooting .380 +p automatically voids your warranty.

      I would point out that the 9mm Makarov is traditionally considered to be slightly heavier and faster than .380 (generally 95 grains @ 1,000 fps vs 90 grains @ 900 fps). Also, Wikipedia (I know, I know) lists the SAAMI (or CIP) pressure specs for the 9mm Makarov as being several thousand PSI higher than the .380. That should allow for a hotter round that’s still within the SAAMI

      • Jeff Smith

        Also, ammo prices for steel cased Russian 9mm Makarov (FMJ and JHP) can be very affordable. I’ve been finding Silver Bear and TulAmmo for $10-12 per box while .380 seems to be more towards the $20ish price range.

        • HSR47

          I bought a case of PPU .380 around Thanksgiving last year and my cost was in the neighborhood of $13 per box shipped.

          When I eventually reload it, those reloads are likely to work out to around $5 per box.

          • Jeff Smith

            That’s a hell of a deal! I live in the Memphis area and European brands (PPU, S&B, etc.) can be hard to find in stores, but, when found, PPU can be found for around $13-$15 a box. Generally, .380 carried by most stores/shops is Remington, Winchester, or another American brand and runs $20-$25ish.

            Online shopping always helps, but my shooting trips are usually “spur-of-the-moment” and result in me having to make a trip to a shop.

          • HSR47

            I was visiting friends for the holiday, and the company I purchased from had warehouse and retail operations; I ordered through their website, and the case of .380 was the only part of my order that their storefront couldn’t fulfill.

      • Interesting. Perhaps it’s that most 9×18’s are straight blowback/old, and so they are don’t load it to as hot of a +p as they are do with .380, which is fired mostly out of a modern locked breach?

        I’m curious to see what quickload has to say about the two head to head. I believe .380 +P, while not an official SAAMI spec, is generally regarded as round 26,000psi.

        • Sunshine_Shooter

          And that is the beauty/danger of +P. No consistent spec, so every manufacturer does their own thing for their own reasons.

    • Anonymoose

      cheaper plinking ammo, maybe?

      • I only browsed SG Ammo but it didn’t seem as if there was much savings if any. Possibly some more investigation to be had.

        Really wished it was a .32 NAA barrel.

    • J.T.

      “However I’m not sure what real benefit it offers”

      Caliber consolidation. I already have a gun that uses 9x18mm and this barrel would prevent me from having to stock a new caliber.

  • anon

    for what reason

  • Lance

    Looks fun!!! Hope they make a 8×18 G-17 that be fun.

    • Matthew Groom

      A company called VBR-Belgium was offering 9x18mm barrels for the Glock 17 and 19.

      • totenglocke

        Interesting…how would 9×18 work with 9mm magazines?

        • Matthew Groom

          In general, it’s recommended that they be loaded long. If I was to reload some, I would use 150grn bullets intended for .38 S&W in a 9x19mm magazine.

  • Edeco

    7.65x20mm lounge-pistol plz.

    • Matthew Groom

      If someone would make brass for it first, that would be great.

      • Edeco

        I partially kid, but seriousely yeah that round should come back. Maybe too warm for use in a small blowback gun, but there are a lot of compacts and subcompacts with locking breeches now for which I think it’d be perfect.

        • gunsandrockets

          If Savage could fit a 10 round double stack .32 ACP magazine into a pocket pistol, than it should be possible today with the 7.65x20mm in a polymer framed pistol.

    • gunsandrockets
  • Alexandru Ianu

    How’s 9Mak any better than 380? They have about the same stats, and price is similar.

    • Edeco

      extra hundredth of an inch diameter :S

    • Matthew Groom

      You can reload brass 9×18 easier, and it’s easier to make than .380 brass if you don’t have any.

  • Dickie

    Interesting but is it reliable with current extractor and magazine.

  • Harry’s Holsters

    I’m sure they’ll sell a few but I’m still missing the point of this. 9×18 isn’t cheaper than 380 and doesn’t offer more ammo options or power. It’s also less available.

    9×18=slightly more expensive, not available in most gun shops, less options for defensive ammo, same to less power.

    I’m just not getting it.

    • totenglocke

      What are you talking about? 9×18 is usually $10-$15 per box cheaper than .380 for target ammo.

      • HSR47

        Wait a minute… Are you saying that you know people who are willing to pay me to take ammo off their hands?

      • Harry’s Holsters

        Where are you buying your 380? They are ripping you off. Ammo search engines all have 380 slightly cheaper.

        • totenglocke

          I haven’t looked at .380 in awhile (I never owned one due to cost, but my girlfriend had a .380) and for years it used to be around $20 a box while 9×18 was $10 a box.

          • Harry’s Holsters

            That was back when pocket pistols and CCW first took off and you couldn’t find 380 ever. Now everyone and their mother owns and and production has caught up.

    • gunsandrockets

      Just checked luckgunner for cheapest pricing and 9mm Mak is only 21 cents a round while .380 is 24 cents per round.

      • Harry’s Holsters

        Impact guns has 380 for 18 cents a round. Cheapest I can find Mak is 20 cents. Not overal cost savings wit the mak round.

        • gunsandrockets

          I just checked impact guns myself, and the cheapest .380 ammo they had was 28 cents a round, not 18 cents a round!

  • Derek

    What’s next, a 7.62×25 glock 43?

    • Harry’s Holsters

      Now that I could get into!

    • Matthew Groom

      It would have to be a .45 or 10mm conversion (21, 20, 40, 41, etc) due to the length of 7.62×25.

    • totenglocke

      I’d absolutely buy a conversion kit to switch a Glock (preferably one I could use for a Glock 19 or bigger) in 7.62×25. I’d love to have a super high capacity Makarov as well.

      • Anonymoose

        I just want a semi-auto OTs-33.

        • BearSlayer338

          I’d settle for a semi-auto Stechkin.
          The Makarov’s bigger,higher capacity(20 round mag) Cousin.

    • Anonymoose

      Teppo Jutsu did it with the Beretta 92 and Norinco and a couple American companies did it with the P226 and 1911, so I don’t see why not! lol

  • Matthew Groom

    According to Michael Manwill of Lone Wolf Distributors, these have a proper bore diameter of .364″, too. I have an old conversion barrel for my IJ-70 Makarov that was .356″ diameter, and it would get hot very quickly. It did not inspire confidence.

    I love the 9x18mm Makarov, because I can reload it. I have, in the past, attempted to reload .380 ACP with very poor results overall. The brass is VERY thin on .380 ACP cases, usually thinner than .22 LR cases. This results in bulges and “waists” being formed when the bullets are seated, and every brand of brass is different.

    9×18, however, can be made out of shortened 9x19mm brass (which is laborious, but not difficult) or you can buy it. Combined with a very heavy recoil spring from Wolff Gunsprings, I load my 9×18’s HOT. Noticably hot, but even my numbers don’t match the velocities and energy stats posted by the likes of Underwood out of an actual Makarov barrel. I seriously, seriously doubt they get numbers like that out of a shorter .380 barrel.

    • Per Mousegun Addicts testing (fantastic blog for ammo tests) the .380 +P Gold Dot did 1113 ft/s out of a 2.5″ Kahr barrel, so they would likely meet or exceed 1175 out of a 3.6″ barrel like the Makarov.

  • Don Ward

    But… but… but… Nicholas C DISMISSED the Glock 42 because it ONLY fired .380 Auto. Now he’s INTRIGUED because it fires a completely similar performing projectile.

    Let’s see what the comments section has to say!


  • Kelly Jackson

    I’d love to see a Glock 19 sized gun in 7.26x25mm

  • Random Disabled Person

    And the bigger question is why hasn’t Glock already released these models for the 9×18 and 7.62×25? It not like the extra model numbers would matter, the x18 wouldn’t be for a Glock 18…

    Both sides(fan boi’s and haters) say what you will, but Glock could have done a better job of making their numbers has correlation to their caliber or groupings for mags.

  • whskee

    I agree, choice is good. It’s just not one I would make personally. Perhaps this is better for overseas customers? I love that I can convert any Glock in .40 into a .357, 9mm, or .22lr. Glocks are certainly more modular in caliber conversion options. I don’t own one in 45acp but there is a long list of conversions there too as I understand it.

    • Tierlieb

      Yes, conversion systems should be big sellers in countries that limit the amount of guns you may have. Surprisingly, it turns out they are not. Probably because for more purposes, they don’t differ much – as Tom Givens says “pop guns”. It’s not like there are rifle-level differences to be had.

      And talking about the big Glock frame: 45 ACP only gives you 10mm Auto and a bunch of boutique rounds (.50 GI, .400 Corbon, .460 Rowland, .45 Super and whatever other 45/10mm case necked down to 10mm/9mm there is…). Ideally, there’d be a 7.62×25 Tokarev, but those seem one-off jobs.

  • themonkey69

    .380 is 9×17, Makarov 9×18, 9mm is 9×19 not that big a difference.

  • Cal S.

    So this will come in handy when the SHTF and we collect the spare 9x18mm off the Nagant-toting, Russian-Cosplay prepper we just wasted?

    Cool, now we just need an AR-10 upper chambered in 7.62x54R and we’re golden! Hey, as long as we’re going for the overpriced alternatives…

    • Xtorin O’hern

      hey an x54R AR-10 upper would be cool as hell

  • PK

    This has been available for over a decade through IGB of Austria. I have an EDC G19 in 9x18mm.

  • iblis

    I would love a 7.62×25 Glock! The Glockentok! If someone makes it-I will buy it.

  • AKSU

    I like my G42 as is. Soft recoil and fun to shoot. 380 has killed plenty of people.

  • “I had dismissed the Glock 42 since it shoots .380”

    Ever shot one?

    • Nicholas C

      Yeah at shot show. Didn’t like it compared to my PPK/S

      • You prefer the heavier, harsher recoiling firearm in the same caliber? That’s interesting.

        • Duray

          Don’t forget the sharp edges on every outer surface.

  • Darhar M.

    I might be interested in this if having a Glock was not involved.

  • gunsandrockets

    That’s interesting, don’t know how I missed that when I looked.

    Of course that is the only place I can find where .380 undercuts the price per round of 9mm Mak. Just that one impactguns case of 1000 rounds of Tula .380.

    In every other place, in every other quantity I can locate, for the same brand, 9mm Makarov is cheaper than .380 ACP. Including the impactgun prices for 50 rounds of Tula ammo.

    • Harry’s Holsters

      Go on wiki arms or the other ammo search engines and you’ll see it’s not the only place. Plus with the minor price difference when it’s not you have to buy a ton of ammo to make up the difference. At 3 cents a round difference you have to shoot over 5k rounds to see a difference.

      • gunsandrockets

        Okay I just did. I just used 6 different ammunition search engines and only one of them showed .380 cheaper than 9x18mm, the very same impactguns case of 1,000 round from Tula mentioned before. All the other search engines showed .380 either as equal to the cheapest 9x18mm or more often as slightly more expensive.

        I don’t buy the claim that .380 ACP is cheaper than 9mm Makarov. The impactguns deal for a case of ammo seems like an anomaly.

        • Harry’s Holsters

          On the first 50 results of wiki arms 380ACP goes from $0.18 to $.25 a round. For 9mm mak is was $.2 to $.26 a round. They are close but 380 is cheaper and there were some brass none reload options in the 380 lineup. None for the 9mm mak. You’ve really got to work to make 9mm mak seem more expensive. And if there is ever an import ban it’ll definitely be more expensive. All the ammo on the first page except a few 380 rounds are imported. If you want to shoot 9mm mak out of a 380 awesome! Just don’t tell yourself it’s to save money.
