Short anwser once is enough. I'm not going to shoot a gun that gives me pain. I only shoot magnums out of all steel guns. Just too many choices out there on the gun market. I see people that have no clue buying lightweight .357's and then are afraid to shoot them or develop bad shooting habits.
I shoot often and most are low pressure 38 spl's or 45 acp. When I move up to the harder shooting rounds I also move to heavier guns. Most of the time when I go to the range I'll put 300 to 500 rounds down range and sure couldn't do that if I was in any pain.
