Nutball763, based on a report of replacing the standard barrel with an after market, I have ordered a KKM 40 to 9 barrel for my V-Tac and a Storm Lake for the FS. Report is on the 18-8 webb and looks very well researched. Dated 6-24-12 and goes into the reasons for the poor accuracy of some M&Ps. Will report when barrels arrive and I can get to the range.
