In approximate order:
1. Various S&W revolvers, from 1984, and to some extent today. (.38 Special, .357 Magnum, .44 Magnum, .45 ACP, .41 Magnum.) During several different time periods, I carried almost nothing else. The S&W herd became thinner when I started liking Rugers. I have not shot big-bore Magnums since the very early Nineties, when I finally admitted to myself do not have long-enough fingers, and also noticed it took a while to recover from shooting big bore Magnums, an indicator of possible cumulative damage. (See #14, below.)
2. HK P7, 1985. I could not shoot them as well as my revolvers, and when going through a divorce, I had to severely thin the herd.
3. 1911, from some time in late Eighties, and still currently carry them. My first 1911 was my first handgun, in 1982 or 1983, but it was not reliable enough to carry. My Stainless Commander was reliable f0r a while, but then started choking, so I switch to a P220.
4. SIG P220. 1991-1993. The heel-clip magazine release sometimes snagged on things, allowing a partial mag drop. I returned to mostly using revolvers
6. Ruger GP100, 4", from 1993, steadily until about 1995, and sometimes still carry them. I worked two 4" K-Frames into the carry equation in 1995, and kept carrying mostly this mix of .357 revolvers until 1997, when I largely returned to the 1911 system.
7. Browning Hi-Power, .40 S&W. A brief experiment about 1994.
8. S&W 3913 and 3953. Another brief experiment in the early Nineties.
9. Ruger SP101, from the late Nineties, and still do so.
10. Kahr K9, a brief experiment in the late Nineties. It could not displace the SP101 or S&W J-Snubs.
11. Glock, .40 and 10mm.
12. Ruger Speed Six. Still have it, though it is now more of a shared "house gun."
13. SIG P229, .40, because I had reached a plateau in accuracy with Glocks, which I instantly bettered by switching to the P229.
14. Glock, 9mm, because the .40 Snap & Whip and the high bore axis of the SIG were starting to produce pain in my aging wrist and hands. My chief authorizing 9mm as an alternative duty cartridge was a career-extender for me. (The big-bore Magnums, fired in the Eighties, probably did most of the actual damage.) I had started phasing 9mm Glocks into my personal-time carry as early as 2012, and the complete switch happened in October 2015. I still do not shoot Glocks as accurately as SIGs, but sometimes one must compromise, in the real world.
My main carry guns, today, at least in urban areas, are G19, G26, G17, and full-sized 1911, listed in no particular order. I have one police duty rig set-up for Glocks, and another for the 1911, and I qual with both systems. A G19 works best in the severely cramped interior of the new Ford Explorer-based Police Interceptors, especially when riding shotgun, in the right front seat, as any pistol grip that extend more than that of the G19 tends to catch on the seat bolster when trying to make a quick exit.
In rural areas, I still like revolvers. When I retire from LEO-ing, as soon as November, I will be spending much more time in rural areas. In Texas, the .357 revolvers, mentioned above, will suffice. For travels to places where bigger mammals walk the earth, my Ruger Super Redhawk Alaskan might see some amount of carry.
