You missed a calibre....
....but once you play with 10mm handloads all the other options just seem to take the back burner
The unfortunate part is to get the 10mm up to its peak in a Glock you need an aftermarket barrel...

Are you saying the stock G20 barrel can't handle full power 10mm loads?
Never heard that one before. I better tell my buddy with the G20 running hundreds of fullhouse loads using 800-X powder he shouldn't be doing that.
Good thing I have an aftermarket 10mm barrel for my G21's. Should be good to go![]()
Its a 10mm, go big or go home. lol Still haven't bulged a case with the stock barrel though.
I also shoot 357 sig with mine. The price of 9mm with the potential of real thump. Would love to share some loads with another 357sig shooter, data is lacking.![]()

Does anyone have experience with the Glock 29 and Glock 20. Wondering if there is a difference in the felt recoil if shooting the same ammo between the two 10mm models.

I also have a 9mm (9x19) conversion barrel for my Glock 20SF in addition to a .40 S&W conversion barrel.

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
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...
