This forum is generally critical of S&W M&P 9 accuracy and also of .40 S&W in general.
The S&W M&P has a reputation for decent durability with .40S&W, and in general as a soft shooter, and the .40 S&W versions are not plagued by the 9mm versions accuracy issues.
Is the M&P the gun that may be a better choice in .40S&W than in 9mm? For instance, for somebody that really likes the feature set on the M&P, but is concerned about potential accuracy issues with the 9mm versions, would they be better off choosing the M&P in .40S&W?
