PROMAG SIG P938 9MM 10RD BLUE STEEL - 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin

Can’t hold in all 10 rounds it double feeds or just send round up out of place. Bad purchased

These Magazines does not work. I found pieces of black plastic inside my gun from the magazine, most of the time have feeding problems and gets jammed. I just bought 2 pieces and with both mags had the same problem. I own other magazines and have no problems at all with my Sig P938.

Like the regular 6 round mag. Worked first time through then went down hill fast. Maybe the springs are to strong? At one point it launched two rounds out like rockets as I racked the slide.
In the bottom of junk draw with its smaller sibling.

Magazine worked fine until the last round, it would not chamber the last round completely. The 7 and 6 round magazines from sig that came with gun work perfectly fine no hang ups. I would not purchase this product again.
