Just got one the other day, I love it. Very fun to shoot, a day at the range is much cheaper now. I may have to buy an M&P so I have a rifle and pistol that use matching magazines, I have a Ruger 9mm at the moment. It is heavy with 2 fully loaded mags in the buttstock, the recoil is minimal and it is very fun and very accurate. I have about 500 rounds through mine now, have yet to have a misfire.

A fellow Lefty….I have one and love it…I’ve had the keltec and I don’t like it….too many modifications have to be done to get it here it’s readily usable…the smith with sights is ready out the box…and the M&P 9mm mags are useable with the FPC

Pull back the charging handle to release barrel from the handrail or you’ll eventually strip it and it won’t lock anymore, it’s also a bolt stop not release. Smith recommends dropping an empty mag in pull the charging handle and it’ll release the bolt stop

23 round Magazines not 22 rounds.

A lot of people compare it to the Keltec. I've also owned the Keltec and this is way better.
