My very first pistol was a Smith and Wesson model 59. After a couple of years, I went with the 4506. Then, the Sig 226. I eventually wound closing out the Millenium with a 229 in 357 Sig.
Along the way there was a Taurus Millenium, which had an awful trigger. I once owned 4 different 1911s, but while they are nice looking, they were too unreliable and difficult to keep running, so I sold them and switched to the M&P series. I also frequently carry my J frame.
The pistols I remember owning, even though I am sure that I have missed a few.:
M&P in 9mm, 45, 40 S&W
Shield in 9mm and 40 S&W
Sig 229 in 9mm
Sig 229 in 357 Sig
