Glock 20 Three in one!!!

If you haven't Glocked a 10mm case yet your either lucky or haven't tried hard enough yet

Trust me... Start pushing 155xtp's with copious ammounts of power pistol or 200xtp's with LOTS of 3N38 in a stock barrel and it will happen

Mine is a 2009 G20c and the chamber looks like it takes up the whole case... It does not.

10mm is one of life's finer treats... A good cigar... A well corked bottle of wine... A shot of smooth tequila... A super sonic 180gr bullet fired from a large frame semi auto with NO muzzle rise.... Ahhhh... The brotherhood of the 10mm.

Its not really the barrel so much as the chamber. The large tolerance stock one bulges (and prematurely kills) your brass, especially the unsupported part on the feed ramp. The Glock smiley is no bueno.

Check to see how the G21 extractor works with the 10mm rim and your conversion barrel. .45 is quite a bit fatter, so you might see some FTEs. Maybe, maybe not, but that is the only issue I can think of with your proposed setup. I'm like B and run two slides so I can't say for sure, just a thought

Enjoy the 10mm. My favorite pistol round by far.



EFK Firedragon used to make them (maybe still do, can't find them on their site). I recall a guy on either TFL or GlockTalk having one... I remember clearly it was an EFK though...

I've only fired a couple hundred factory Remington green box 10mm with my conversion barrel. Not a single failure of any kind yet and I just bought 20 and 22 pound springs to try to get the brass to stay a little closer to me. It flicks the brass about 10 feet to my 5:00 with the stock spring. I figured when I get time to build some handloads I better try to slow down the slide a little.

Does anyone know if the conversion barrels for the gen 3 glocks will work in the gen 4's? I might have to buy a gen 4 21 instead of waiting for the new 20 if they will work.

I don't see how any mags would feed a 9mm bbl. 9's won't work in my 10mm mag. I just checked.

Are you mags pinned to 10 rounds or are they the factory 10 round magazines? My 9mm conversion does not like the pinned mags as it will not strip off the last round in the magazine.
