I have a P3AT that goes in my pocket everywhere. It's about as convenient as a gun can get. This is only my back up gun, but it fills the role well.
I have about 50 rounds of FMJ through it and about 20 Hydra Shocks. The first few magazines through it, the first round would hang up on the feed ramp upon charging manually, requiring the slide to be pushed forward to chamber the round. Never hung up in actual cycling though.
The recoil is a bit "snappy", but it's perfectly reliable so far. I wouldn't worry about the slide stop one bit. On a gun this small I think it's more of a detriment.
