I pocket carried a 9mm Ruger LCP II, it's single stack and you don't even notice it. However, I rarely carry anymore. Too many rules of where you can/can't carry. I work in DC as fed- can't have it on fed property; retired military- can't take on any base; volunteer EMS- can't carry on department property; some counties and businesses won't let you on there property with one... About the only time I carry is if I have to shop in Waldorf...even then if I had to use it in this gun crazy state, I'd be the persecuted one. I did get the permit years ago when it was "impossible" to get and still keep it active just because I can.
