I saw that Lever Arms in Vancouver has some Norinco Tokarev 9mm mags for $15 each...
Thanks for the info about repairing the feed problem. I just got my 213 last week, and have yet to shoot it. (hope I don't have the same issues as you did). My buddy has a 213 and the original (1945) "grandad" TT33 as well, the pistols look almost identical except for the markings, slide grooves, and the lack of the "CCCP" on the grips of the 213.
I also own a Norinco M14S, and noticed that the fit and finish are far superior to that of the 213. (very rough, with lots of machining marks everywhere...)
Ah well, what do you expect for $100?
