Having experience with the M&P, the Walther and the SR...the SR is the most well received by shooters, especially the new ones.
Of the three, the SR22 generally performs best. It cycles all the ammo, It's ambidextrous, has good balance, it's accurate, works fine dirty, and fits 90% of hands.
It is my go-to when teaching semi-auto's to new shooters. Because of it's no worries performance, it makes shooting fun. Critical with new shooters, as un-fun is the #1 reason they don't wanna keep playing.
Two things to pay attention to; the rear sight can drift out of alignment. Pull it off, dab blue locktite in the dovetail. Stays put after that.
Limp wristing can cause failure to feed problems. First thing to check before going after ammo and tearing the gun apart.
Having favored magnum revolvers just about all my life, I find myself playing with the SR all the time. Consistent quarter size groups from 20 feet offhanded...what's not to like?
