1. First read Posts #36 and #66, then come back. Okay, but that's because a J frame except in the most expert hands rarely provides proficiency with quick accurate follow up shots. A 37 oz. N frame 8 shot or L frame 7 shot of +P will cut it. A civilian self defense scenario requiring 35 rounds (9mm chambered full size Glock with spare mag) is as statistically probable as getting hit by a meteor, and you don't prepare for that either. I have 46 rounds on duty (Glock 34) because a running gun fight while spectacularly unlikely might happen. Off duty that won't happen, and I am qualified with my agency with a 586 L-Comp 7 shot revolver.
2. Or because we are white? Please. We have the lowest homicide rate of any of the three most populous ethnicities in the U.S. by a wide margin there Barney.
For preparation for what will happen, get nite sights.
