I've been loaned 1 to make holsters to fit all the full size and the Glock 19 ( the baby Glocks I dunno if they are slimmer or something, the guy who lent me does not have any of those). I was told they are all the same frame size, just different barrel lengths and grips may vary a little. I don't need to worry about the grips though to make holsters. This gen 1 has no rail, and I am wondering if the later Glocks with rails are any thicker around the slide/frame where the rail is.

BTW, the 22 gen 1 fits my XD holsters with a bit of wiggle, ie breaking in is required.

Hee hee hee he included a mag, and he said I could "play" with it if I want.
