  1. Adam Bailey (verified owner) –

    This kit contains hands down the best mag release for the JM9 currently. 100% fit capability and super solid, the screw wasn’t great though as the threads weren’t taken all the way down leaving it loose when screwed down. To remedy this I just used some lubricant and used the screw to tap its own thread further down.
