Have a S&W 686 6" barrel that isn't my carry. That said it would be if need be a home stopper for an intruder. I have a variety of loads for it, but from what I've read and talks with coworkers you would be nuts to fire it indoors, likely at night, as the muzzle flash and sound would both be deafening and blinding with .357 loads. Not to mention risk of passing through walls etc. I have .38 SP and .357 wadcutters that I have heard less muzzle flash that would work better in a defensive situation. Opinions?
