I must say I am not a Glock fan. I'm not going to get into that here, though. I get lost in the sauce when someone just talks about his Glock by its number (EX: G19, G35, etc). I don't know what all the numbers are. I always have to go to glock.com to figure it out. That takes forever. So I wanted to just make a thread, mostly for my own reference (but hopefully someone else will find it useful) that I can quickly go to to know what caliber/frame size someone is talking about with all these numbers. The number in (parentheses) refers to the standard capacity magazine size. 9x19 Parabellum Glock 17 - full size (17) Glock 17L - full size; competition; longer slide + barrel than Glock 17 (17) Glock 18 (fully automatic) Glock 19 - compact (15) Glock 26 - subcompact (10) Glock 34 - full size; competition (17) .40 S&W Glock 22 - full size (15) Glock 23 - compact (13) Glock 24 - full size; Glock 17 frame with longer slide (15) Glock 27 - subcompact (9) Glock 35 - full size; competition (15) 10mm Glock 20 - full size (15) Glock 20 SF - full size; slim frame (15) Glock 29 - subcompact (10) Glock 29 SF - subcompact; slim frame (10) .45 ACP Glock 21 - full size (13) Glock 21 SF - full size; slim frame (13) Glock 30 - subcompact (10) Glock 30 SF - subcompact (10) Glock 30s - subcompact; slim slide (10) Glock 36 - subcompact; single stack (6) .45 GAP Glock 37 - full size (10) Glock 38 - compact (8 ) Glock 39 - subcompact (6) .380 ACP Glock 25 - compact (15) LE only Glock 28 - subcompact (10) LE only .357 Sig Glock 31 - full size (15) Glock 32 - compact (13) Glock 33 - subcompact (9) Is anything on here incorrect? Again, I'm not a Glock guy. This thread is just for reference. For those of you who do know Glocks, please let me know if I should change anything, and I'll edit the post.
