Hmm; 50+ years of age? I am still a bit shy of 49 years old. I started handgunning with a 1911 in 1983, but then had carry what I then considered the antiquated sixgun as a rookie peace officer in 1984, like it or not. Well, the sixgun grew on me, and I am now definitely in the revolver camp, though I still like autoloaders well enough. I later carried 1911s as duty pistols, until 2002, when I switched to Glocks for a couple of years, before settling on the SIG P229.
Now, nearing the end of my peace officering days, I recently purchased my probable primary retirement-era carry gun, a 3.06" SP101 in .357 Magnum. I have long used snubby SP101s as back-ups at work and off the clock, and sometimes as "primary" when off the clock. From 2002 to 2006, I routinely toted two SP101 snubbies on my own time. The 3.06" barrel of my newer one will give me a bit more sight radius, for my aging eyes, and a bit more heft to dampen muzzle rise. I installed a spurless hammer, so the little fivegun will not eat my clothes like a metal moth. I can get all of my skinny fingers on the factory grip; no dangling pinky. Life is good.
Of course, I do still have one 1911; I kept my best one, a Les Baer Thunder Ranch Special. 1911s AND revolvers. Life is really good.
I will admit though, I will probably not tote an auto daily after I put my retired badge on a plaque.
