Mine operated perfectly with several different ball and hollow point loads.
I emailed them about the possible thumb safety issue and was promptly sent a return mailing label. Smith kept my pistol a grand total of nine business days, and it’s back in my hands and will see some more range time tomorrow before it assumes it’s role in my carry rotation.
Waiting on an OWB2 holster from JMCK.
I appreciate Smith’s fast response to the “problem”, and that’s just one reason I’ve spent money from a fairly modest income over the past year or so to buy eight M&P’s. Did I mention how much I like the 2.0’s?
