i am quite experienced with smithing a 1911, so i can go through one, do a little work on it, do a few checks and know its good to carry without even firing it.
as for how much i shoot, i shoot 2-3 times a week. last year i went through about 40,000 rounds of just 45acp. all in all i probably fired about 55,000 rounds last year, all calibers combined.
my range i go to does a simulated police qualification course as well. i cant remember the last time i shot less than a perfect score.shooting our local "bullseye" competition, i shoot a perfect 150 strong hand only and both hands, weak hand only i tend to shoot about a 145. scoring based on 15 shots with bullseye being a 10, shooting at 5 spot targets.
i like the wilson 47d's in my 1911s, but these new springer magazines seem to be doing surprisingly well.
