OP have you held each one yet? held the sr22 with both grip sleeves?
the m&p does not have interchangeable back straps like the rest of the line does, it's the medium size. and the m&p is dao while the sr22 is da / sa hammer I don't know anything about the p22.........
Huh? the MP2 is not DA/SA, and has no hammer.
It sounds like I'm going to be buying a M&P 22. Thanks everybody for your input.
