I was involved in a shooting where a total of 9 rounds of 357 Mag. were fired in a small kitchen/dining area of a house. It was dimly lit during the early AM hours. Neither muzzle flash nor noise bothered me DURING the incident. However, I have permanent hearing loss and tinnitus to this day. That was over 40 years ago. What I remember, most vividly, was telling myself to look at the front sight. Training matters! I am a firm believer that one fights as he/she trains.
