Hello all, got a bit of a mystery that google hasn't been much help with. An Army buddy recently acquired several guns from his aunt, one of which is a Glock 19, generation unknown, with only one pin. It's strange to me because I'd always though Glocks had a minimum of two pins: for the locking block and slide catch.
Any of my fellow gun lovers here ever seen such a thing?
