Purchased this over a decade ago for my Brothers college graduation, he wanted a good SD/HD handgun. LEO trade from a local metropolitan police dept, even has MPD in the serial number and the PDs badge logo rollmarked in the slide which is neat. Glock 22- Gen 2 - 40 s&w. "Restricted" LEO magazines, i think this gun was from the mid 90s and probably was in LEO service through the early 2000s. It has been 100% reliable for him since. It is doing a funky thing now, where if the slide is locked back and a loaded magazine is inserted with any kind of force, the slide goes into battery on its own [auto forwarding] without thumbing the slide stop or slingshotting the slide. It goes into battery, and fires fine from there, but its still a problem. Possibly getting new magazines will solve the problem, because the problem is the worst with the oldest, most worn ones of the batch. Any experiences? Id like to believe that this gun still has decades left in its life, and with some minimal TLC or replacement parts, it will be running like a new one and continue to be his go to firearm he bets his life on.... insights? Would you recommend just moving on as its nearly 30 years old and possibly not worth betting life on as an only carry piece? When do you call it quits, even with a Glock?
