I have a 1991 G17 (early gen 2) which I bought new in July 1991, along with 3 G17 mags.

I also have a G19 (late production gen 3) which I bought new in 2009. I have found that those old G17 mags are not reliable in the much newer G19. They work well most of the time, but occasionally the slide locks back when there are still rounds in the mag. I also had a couple of FTFs. In the 20 years I have been shooting that old G17 it has never had a single malfunction. I have never had a single malfunction with the G19, except for the few times I used those old G17 mags.
