I haven't actually stuck one in my pocket, but a friend carries one as a "pocket pistol". He loves it, loves how it shoots, says the recoil is very well controlled. I've seen and handled his, but not shot it. IT IS TINY and LIGHT !! It weighs just 12oz with an empty magazine. I take that back, I did put it in my pocket, unloaded though. In my regular, summer cargo-type shorts, I literally couldn't tell it was in my pocket.
My wife wants to get one instead of her Shield (9mm) but apparently S&W hasn't fine-tuned the quality on all of these yet. Lots of complaints about the sights being off (shoots to the left), can't fully load the magazine, etc.
