I have a trade offer for one of my rifles involving a glock 21 gen 1. I've never owned a glock but I have picked up a few things about them in the past year or so. My understanding is that the main difference in the different generations refer to the grips ( if I'm wrong please educate me). My main question on a gen 1 glock 21 is what is the absolute newest that it can be? When was the gen 1 discontinued? My concerns are the gun being worn out, especially the barrel. I haven't seen the gun in person, but looking at the pictures I wS sent it looks like a brand new gun. Any insight will be appreciated.
Thanks,
Derrick
