When I was younger Skunk I carried for the most part Model 19s and 1911s alternately, on and off duty. My favorite at the time in small revolvers was a nickel plated Colt Detective Special. It was strictly backup. I trusted the revolvers much more until I started building 1911s, and then it eventually became an all around issue.
I was forced to use a pistol involving three cars on three seperate occasions and the 357 mag way out performed the 45acp in all instances. The last instance was with a 45acp, and I sold the 45 the next day. I gradually went back to them, but it was always in the back of my mind "what if". "What if" never happened again, but in the end, at 60 years of age, I trust the revolver more, as even weak ammo will function without a hitch, and I can be more relaxed in all areas.
I re-evaluated my personal experience over the years, and all the officers I personally knew that had fought with a pistol, and decided that the auto really wasn't as necessary as most think, and what it really took, was the will, and know how, to win. Many on the auto wagon will disagree. That's ok. I been there, and I am comfortable with my decision.
