This is a G-21, 45 auto. I just assumed since it didn't have a "gen 3" stamped on it, that it was a gen.1 . Can anyone confirm? All the numbers match, by the way.

My Glock 23 Gen3 doesn't have a "Gen3" stamp anywhere on it. I don't think they started putting "gen" stamps on the slides until "gen4". So I assume that it's a Glock 21 Gen 3.

Correct. Only Gen4 says "Gen4"

Just to be clear, Gen1 was G17 & 19 only. Everything else is Gen2 or later.

It has the finger grooves but the texture doesn't match the sides. That's easiest way to tell Gen3. Gen2 didn't have FGR (finger groove rails). If its Gen4 but you can't see the left side of the slide look for the FGR and the side texture to match the same texture in the grooves.

You think we can apply all this schooling we get in here toward a Bachelor's Degree of some sort?
Maybe, If we all plan on being bachelors!:confused:

Then I guess I technally should've called it the "first interation" of the g21
A lot of people don't realize that the 1st Gen was so limited and call the Gen2s Gen1 because it was the first generation of that model. It can get confusing, and not just with Glocks!

For a long time after the Gen3s came out, Glock refused to recognize them by generation. It was only on the Glock forums that people referred to them by generation. Obviously, by Gen4, Glock got on board. :)

Still going to school here. Thanks guys...
One day, if you study hard, you too can be a Glock Master! ;)

For Gen4 you can also just look for the backstraps. It's obvious, even if there isn't one installed.

I think we should use more of a belt system...eventually you can achieve a 3rd degree blackbelt in Glock-Fu!:D
