    KNS pins are one of those issues where people who are in the know will never agree. Some very well respected shooters and instructors hate them. Others will never have a serious gun without them. However it isn't the anti rotation they are worried about. It is the pins walking.

    I've only seen problems in F/A. In semi, should not be an isse. Might be time to send it back or get a gunsmith that knows what he's doing.

    The hammer pin hole in my brother's lower is worn to bare aluminum from the pin rotating(semi auto). I've always run them, he does now.

    This issue has been discussed many times. Pins walk loose because the LPK is installed improperly or something is worn or out of spec. How you install the pins make no difference as they are the same dimensions.

    KNS pins are not the solution.
