I received my magazine it appeared in good condition but when I went to load it the follower was sticking so I took it apart it had some surface rust inside it cleaned up pretty good other than that it is in good condition and now functions perfect I would have given it four star but shouldn’t have to clean rust out specially when you pay as much for it .
Expect that you may have to slightly radius the mag catch slot with a Dremel as there are many subtle variations in the manufacture of these firearms over the years. Still far superior to the reproduction part polymer mags on the market today. Holds and feeds rounds perfectly. I purchased 3.
