Good alternative to oem sig mags - Armscor Precision Inc Act-Mag SIG Sauer P320 /M17/P250 Full Size, 9mm Luger, 10 Round, Pistol Magazine

This is a good reasonable cost mag to the Sig oem ones. Almost half the cost. The follower movement doesn’t feel as smooth as the Sig mags when pushed with my fingers, but works just fine. I plan to get more.
