i know ill catch flack for this one... consider a glock 19. falls somewhere between a full size and a compact size gun. reliable, shootable, concealable. that said, i carry a full size M&P 9 in a galco kingtuk holster. works for me fine. i too love j frame S&W revos. own 6. carry one in an ankle rig alco from galco. might also look at the Ruger LCR. i love my smiths, but own other brands too...
