My experience with the latest ones has been with three-inchers. I see no reason why the two-inchers should be any different.
S&W really seems to have gotten the MIM process down. When I re-took the M&P Pistol armorer course about a year ago, we were told that they had shifted to a stainless-steel alloy for MIM. In any case, they seem to be getting very good dimensional consistency and correspondingly nice actions. (I recently re-sprung three Classic Series Model 40's for a student. I had intended to use 13-pound rebound-slide springs but inadvertently ordered the 11-pound springs. To my amazement, they gave reliable trigger return.)
LaserGrip? Maybe, so long as she doesn't think of it as a substitute for learning to shoot. (More detailed comments on
my own website.)
