I'm a little late on the ball game here (see my introduction) but I have a promag 20 rounder that I got about 6 months ago that works as good as Check-Mate mags. It is a little harder to get in the mag well but it is a solid mag for the money.

Verified vintage USGI mags, current USGI mags made by C.M.I. and Norinco/Poly Tech mags are the ONLY ones I will use.

Be careful not to buy counterfeit vintage USGI mags, plenty are floating around.

The Norinco and Poly mags are pretty good? I haven't got to see one in action. I like my pro-mag, but I may have got a screw-up (aka a good one.) I bought it because pro-mags work in my Mini-14 and 1911, and 44mag was out at the time.
