Does anyone know any good ways of increasing the odds of a psychological stop?

I heard from guys like darrel bolke say that part of the reason for the 125 gr 357 magnum's excellent reputation was it's large muzzle flash helped the bad guy realize that they'd been shot. Obviously physiological is better than psychological but a stop is a stop and especially with handguns I'll take what I can get. via /r/CCW https://ift.tt/3DWZzin
