I'll second the S&W 48 as my .22 Magnum revolver of choice, mine has a 4" barrel, but I've owned both 4" and 6" versions.
That said, I carry a Rossi 515 more often because it is stainless and until recently wasn't worth much, so if I dropped it or dropped something on it, it wasn't a concern.
I carry mine about like HB does, 3 rounds of CCI snake shot and 3 soft point rounds, usually Fiocchi 'cause I bought a couple thousand rounds of it back when it was seling for less than $2 per box.
I wish that S&W had made a stainless 48 that didn't have an ejector rod shroud, an exact copy of the 17, 18, or 48.
