  1. New M&P 9 Full jams every time on last round (pics)

    MP Full Size Pistols
    I've shot 150 rounds through it now, and on the last round of every magazine, it jams. Sometimes it happens on the second to last round also. I've used 2 types of ammunition and it still happens. This happens using both factory magazines. It even happens if I only put 3-5 rounds in the magazine...
