Funny, I've been having the same problem with my M&P Pro; I even used Storm Lake barrel and KKM, but the precision is still disappointing. At 35 yards, the best I can get is 8-10" group and even that isn't consistent. Even tried a half-dozen brands of ammunition, which created different size groups, but nothing better than 8-10 inches. At this point, I've realized that perhaps my shooting ability exceeds the capability of the gun, so it's time to look at something else. However, I'm only interested in production division shooting, so I'm considering switching to a CZ pistol from Matt Mink.
I am very interested in hearing feedback from elite "production division" shooters that are former M&P users. Did you find a solution to improve precision of your M&P Pro? If not, what did you switch to? And was the switch worthwhile?
