Glock Generations

[Bear Wallow]

Was there a 1st generation G22?  Sorry if that's a dumb question.

I think that I basically have this right.  As I recall, in the early/mid 90s there was an upgrade available to G22s that involved several parts in the slide, including the extractor.  After a certain point, that upgrade was incorporated into the manufacturing process.  I don't know if that counts as a generation or not.  Also, the frames now incorporate finger grooves on the frontstrap and a pic rail in front of the trigger guard.  I'm not sure when that happened...maybe in the late 90s.

My G22 was purchased by me new from the factory in about 94 or so, and the slide changes had already occurred, but it has the old style frame.

Clear as mud?

Thanks for the detailed info Mainspring!

hope this helps:

1st Generation has the smooth, rounded “pebble-grip”.
- 2nd Generation has the “Grenade-style” checkering with NO fingergrooves (see picture).
- 3rd Generation has BOTH fingergrooves AND accessory rail on the front dustcover.
- If you have a subcompact (G-26, -27, -28, -29, -30, -33, -36) OR a “transition model” when Glock was putting fingergrooves but no accessory rail, then you have a 2.5 Generation. There is even a slight variation here, as some of the earliest G-26 & G-27s had smooth fingergrooves, without checkering in-between the grooves. Some people do not count the sub-compacts as 2.5 Gen since they came out after the 3rd Gen frames were already being made. Note: newer -29, -30 are now coming with rails.

The upgrade does not count as a generation. Generations are only cosmetic frame differences.
