I once bought a gen3 Glock 22 from a friend who needed the money. Not being a great fan of the .40S&W round, I used the pistol along with a model 31 barrel to familiarize myself with the .357SIG round. Once that was out of my system, I sold both the pistol and extra barrel.
I have models 17 and 19 with Trijicon night sights that are both early gen3 2-pin pistols. I feel no real pride in ownership for either but they certainly are accurate and reliable. Those 50 round drum magazines tend to make them more fun.
