Ehhh. just ok - Agency Arms Sig Sauer P320 9mm +5 Pistol Magazine Extension

These look cool and I love the anodized green BUT wow what a pain to install. Had to file down the tabs on the magazine to get this to slide on and then press in the center so the locking set screw could even go in. May just throw these away when the magazines need cleaning, it was that much of a pain.

Other than that, they’re great. Easy to grab and look great with my gun build.
