I'm not so concerned with noise (any handgun fired indoors will make your ears ring), but .357 Magnum JHP loads have a tendency to penetrate like nobody's business. I don't want to nick the perp and shoot through three sheets of drywall, a door, Fluffy the neighbor's dog, and the nice lady next door as she's sitting in front of the TV. It would suck if her Ally McBeal episode got interrupted by a 147gr. JHP to the melon that left the barrel of my 6" 686 at 1400 fps.
My 686 sits on my nightstand loaded with .38 Special +P Silvertips.
