When I started as a cop in '86, my first dept was a war zone. 150 cops and 18 officer involved shootings the first year I was there. The weapon of choice was Colt .45 1911, cocked and locked. I had been a revolver shooter up to that point and I was issued a model 19, .357.
I chose the S&W 645 with double action on the first round. I practiced 200 rounds a day, 5-6 days a week for 2 years there. Always burned 200 before going on duty. They did not mind.
Out of 160 lockers in the locker room, 12 had half inch holes in them. None from me, thank goodness, but my partner had his .45 fall out of his holster and go off when it hit the ground. Fortunately the gun hit my foot when it went off, the bullet went the other way.
Be safe peeps.
