I think you would be happy with a 4" barrel or shorter K frame if you had a quality belt and holster. I carry a short barreled Ruger 44 Super Blackhawk a lot in a Kramer outside the belt holster when fishing, small game hunting, or just messing around in hog and bear country. I can't tell I am carrying it.

If you can find a 3" barrel, round butt K frame and choose good leather you would be in good shape.
