i have glock 21 i can get a 10 mm barrell and mag for 190 im thinking about it any ideas thanks

glockguy67, Welcome to 10mmTalk!



I'm under the impression that the conversion of the G-21 to 10mm involved replacing the slide and the barrel as well. The extractor maybe spread a bit too far for reliable extractions using the slide fitted to 45ACP brass. The 45 brass is thinner on the extraction rim than the 10 mm. While it maybe possible, I would want to maintain the higest reliability if it were my weapon.

Best of luck to you, let us know what you find out!

ty for the welcome no its just the barrell and mag i thought it sounded too simple maybe i ll wait and find out more

Check out some of the threads under the "conversions, etc." forum here on 10mm Forums. The OP's talking about the 10mm conversion barrel. There are problems with reliable extraction. I feel that there has been some deception involved in some of those pushing the conversion, regarding the reliability of the conversion.

There have been several posts by guys in different forums regarding the problems they encountered with that conversion. Best to either buy a complete G20 upper or just a G20, if you want to shoot 10mm through that platform.

the barrel and mag are fine for range work...

I developed the 45-10MM barrel with Kevin of KKM for my custom 6" longslside. I've shot some 6,000 rds of 10mm out of my pistol with 0, yep zero extraction problems. However, the same can't be said for the std Glock slide. It seems to be hit or miss with individual slides.

BTW, the conversion (whether in the custom longslide or the stock Glock slide) is simply a 45-10MM barrel and mags. There is no benefit in changing out the 45 extractor to a 10mm extractor, but there is a slight benefit to changing out the older, flat sided 45 extractor to the current 45 LCI version as the newer LCI version also has about an 8° cant in the extractor claw as you can clearly see in this side by side.



And yes, this mod is a range toy / hunting version, not a self defense weapon.

ty for replying so do you think a barrell and mag is all i need my glock 21 is a very new model with the new extractor

glockguy67, There you go! Jump on in if you want to try it. You might not have any problems with yours.

I wish someone would make a long slide and barrel for the Glock 29's! That would be wild as all get out!

Who knows, when JR finely gets his longslide for the G20 and G21 on the market he's supposed to also be working on a G24 slide and some others. He mentioned that he should have a longslide version for the G19/23/32 size so who knows. You might want to drop him an email and ask. Couldn't hurt.
