However.....there is an adjustable sight that will work on it but it's not made for it. We stock LPA sights for the 5906 and it will fit the M&P but the dovetail cut is not the same, it leaves a very slight (about .003 or .004) gap at the very bottom of the dovetail. I have one on my M&P and it has several thousand rounds through it with no problems. I've installed that same sight on several other M&P's used in IDPA & USPSA with no problems. I have no idea when, if ever, someone will come out with an adjustable rear sight but I did talk to the LPA people at the SHOT show about it, absolutely no idea if they listened.
