I've got two Glock 22's. One is a Gen II that I picked up surplus, had the slide milled, replaced the night sights, added a 9mm conversion barrel, and ended up dropping the entire gun into a P80 lower that allows the longer 22 slide to fit on a 23 sized grip frame. The other is Gen IV that I also picked up surplus (I think I paid $330). I just recently received the Recover Tactical brace for it, and put some rounds through it last weekend. It really changes the game for me in terms of Glocks. It is compact when folded, weighs nothing, allows for the addition of a second mag on the gun and a light. I can see this package going in the lock box in my truck.
