I am thinking about a Smith & Wesson 22 caliber semi auto. Can anyone give a comparison between the M&P 22 and the Smith & Wesson 22A. I'm sure neither are defensive weapons per se, so it comes down to plinking and target shooting. As the M&P is quite a bit more expensive, is the extra cost justified? And is the 22A about the same grip and fit so it would work as a practice pistol for an M&P in larger calibers?
