When I read your title first thing I thought of was this:
Nice!!! I can't believe there is no mass compliant version of these.
I would love one, I had to go Ruger SR22 instead (still a nice little shooter)
but I would've preferred the M&P.
OP......do you have a range report to share?
Had mine for about a year. Fun to shoot. Has an extended threaded barrel. The range I go to let me try a suppressor. That was really fun. Not as muzzle heavy as I thought it would be.
