The G17 was the first Glock here, maybe anywhere, but when the 19 came out Glock had switched to selling G2 guns. A technicality, but the 1st 19 was on the g2 platform. After a match one day at a club a DEA agent showed of his brand spankin new Mod 19. The rest of the gang had never seen or heard of one till that day. Not much internet then.
There are 2 & later, 3 pin frames, but the 3 pin still considered a G2.
That's the way I saw & remember. If there is better info I'd love to learn. But yeah, the Gen 1's are getting "collectable"
