I might also like the information the OP is inquiring. I haven't witnessed it. They also built some 2 pins, in generation 3, for what it can be worth. 40cal weapons. IMO 180gr ammo provides a excellent alternative when 9mm isn't sufficient and 45acp does not maintain plenty of rounds https://glock22price85173.thenerdsblog.com/40413418/details-fiction-and-glock22
