My most unpleasant CCW was the S&W 360/3460 (I owned one of the former and two of the latter).
With .38 SPL +p, not fun, but no problem. With "real" .357s...kind of like a firecracker going off in your hand....multiple times.
My Kahr PM9, even with 9mm+p+ ammo, is infinitely more controllable and easier to shoot well (easy to put 100 rounds worth of practice ammo through) much quicker/easier to reload, ...and easier to conceal/carry.
My LCP is even easier to carry...although, to be honest, I like the .380 far more in theory than in practice, so I do not carry it.
