Just received one yesterday from Kipp, and put it on my Flat Latch 36. Perfect fit. luangtom, I think the fit problem on your M&P340 may be due to the grips. I had a set of Ajax polyIvory grips on a Mod 60, and could not get a original T-Grip to ever fit right. Was hitting on the grip edge which has a different contour than the factory grip. Some of the new Factory grips now have a different contour than the older grips.
