So I have a glock 23 generation 3 and would like to get a conversion barrel for 9mm to shoot cast bullets and I have a nice stash of 9mm ammo. Can anyone reccomend which brand of barrel will drop right in with no fitting? I figured i would ask if anyone has done it. It seems like a real nice idea as I can train cheaper with 9mm and have no qualms about using it for defensive purposes either. My idea was to get one for the wife also as we both have glock 23's. Thanks

Lone Wolf has a good rep.

I have a Lone Wolf 9mm conversion for my 23. Drop it in and start shooting. I haven't run any cast through it though.

Pretty nice having two calibers in one pistol.

I've heard from a local Glock specialist that the KKM barrels are the best. >> http://www.kkmprecision.com/custom_pistol_barrels/home.php

He says less problems with their stuff.

Thanks for the info everyone. I think Im gonna try one of the lone wolf barrels. For less than 100 dollars I'll give it a shot. I'll have to pick up some 9mm mags too. Then I can shoot my 9mm reloads out of my glock 23. If it works out good I'll get one for the wife's also.

I don't have any experience with Lonewolf or Barsto but I have a KKM on my Glock 22 and am considering getting one for my Glock 20, they are awesome barrels and drop right in.

Couldn't find a KKM in stock anywhere to save my life about 8-9 months ago. Went with a Storm Lake and have put about 2.5k rounds through it without a single malfunction, including running 200 rounds of 9mm in .40 magazines. I was expecting some failures but it's been functioning 100%. I've been very happy with it.

Now that's interesting. I'm going to give it a try. Thanks for the tip.

Please excuse my ignorance as I am very interested but you don"t have to change the bolt to change calibers ?

If you are switching between 40. S&W and 357. Sig, you only need to change the barrel.

The mags work with either also.

There's no "bolt" to change per say. I'm not sure what the technical term is for the area of the slide that contacts the back of the casing, but I suppose it acts as the bolt.

The .357Sig is basically a necked down .40S&W, so the body and back end of the two cases are identical. Same "bolt face" and the magazines are virtually identical. It's just a simple barrel swap.

The 9mm is slightly smaller but many .40 pistols have an extractor hook long enough to hold on to the rim of the cartridge and the barrel chamber centers the cartridge in front of the firing pin. The .40 ejectors are usually able to get enough contact with casing to reliably eject the spent rounds.

Some people go so far as to replace the extractor and ejector with the 9mm specific counterparts for reliability, but I have not found this necessary with my Glock 23 or Beretta 96. In my experience with both pistols even the .40 magazines will feed 9mm without any issues.

Thanks, the 9 and 40 is what I was interested in. Is this the case only with the 23 (Glock) or can other models work ?

I have the Lone Wolf .40 S&W conversion barrel for my Glock 20 and it works fine. Bought it to actually get some trigger time on the big Glock with ammo I can afford. I also have a Stormlake 9mm conversion barrel in my .40 S&W XDm 4.5. Had some stovepipes with reloads to begin with but have since put in a 16 lb recoil spring (I believe the factory is 18 lb) and it runs 100% with factory ammo. I have not tried it yet with the lighter spring and reloads. I have plenty of the 9mm XDm mags but internet reports are that the .40 S&W mags work fine feeding 9mm. The smaller rounds sit higher in the wider feed lips of course. You might want to try it with the Glock although Glock mags are so cheap and available there is not a lot of point. Any of the Glock or XDm .40 (or .357 Sig) guns can be converted to 9mm, it is just a matter of finding a barrel.
