Got the rusted G-22 out of the soak in the parts washer. Pitted slde lock, extractor plunger, extractor, plus a couple other parts. Worse part is the plunger's cut hole in the slide is pitted inside. So am considering mounting the slide in the mill and running a slightly over sized drill bit into the hole to clean it up. I will try a hand turn on the bit first to see if that does the trick.
I just got in a new slide lock and the frame steel insert, plus the recoil spring.
These guns were $319 from PSA. So a good bit can be done, on my own, without going into the, over priced range. But there is a down side if buying anything "as is" and "unseen", especially if you can not do the work yourself. That is the actual point of my post, not a Glock problem, but operator negligence.
