  1. Impressive and Functional 4 Star Review

    Posted by on 16th Dec 2021

    Ordered two of these last month - already fired over 100 rounds per the pair of them. no jams or hangs. They do stick about 1/2 inch out of the bottom of the hand grip but latch in securely and release evenly. Will buy more!
