I sold a Gen 2 19 and a Gen 2 23 last year at a gun show. They didn't stay on the table very long. I had already upgraded all my Glocks to Gen 3's. Can't stand the Gen 4's. I can see the love for a Gen 2, they feel very nice in the hand.
I just checked the safe, my gen 1 with 5 character serial # and proof marks is still hanging out. That is one gun I will never let go
I was originally looking for a Gen 2 G19 but everyone was wanting $450 or so for them, I was not going to pay over $400 for one. I ended up buying a new Gen4 G19 from our local LE Glock Dealer for the Blue Label price of $455 with night sights. I could not get myself to pay for a Gen 2 for the price I could get a Gen 4.
