Too many to name.
A good, smooth shooting .357 is always nice. I really enjoy shooting revolvers, and can sit down with a bucket of .38s or .357s (magnums make this a bit more...uncomfortable) and shoot for hours just taking my time loading 6 in, squeezing 'em off nice and easy, or in short bursts, and then doing it all over again.
Something like a nice 5 1/2" or 6" S&W

or for something with a little more kick, maybe a nice smooth Redhawk in 44 or even a sweet ass kicking 454 casull
