Okay, I'll talk my money. I bought a Model 10 a week ago for $275 ($299 OTD). This week, I paid $500 for a Trooper Mk V. I am seriously considering $595 for a new condition blued Mk III.
I have Smiths, Rugers, a Taurus, a Hopkins and Allen, even two Nagants, in addition to my Colts. My great-great grandfather and his son favored Colts (the former carried an 1849 Pocket Pistol at the Battle of Atlanta while the latter used the same revolver for Turkey hunting). My grandfather favored the S&W Model 10. Me? I prefer my Ruger for mud and gunk work but prefer the Mk III I have for the Farm. The Model 10 is a nice, quaint revolver I bought for fun and because it's cheap.
The Colt lock work is definitely more of a challenge than the Smith, which is harder than the Ruger. Ruger lockwork is the easiest to work with in my experience. But, I have yet to have a problem with a Colt and other than than that 1849, my oldest Colt is a New Service that still works great (it was Dad's). If a 100 year old revolver is still trucking along and my Troopers are considered stronger and easier to work on, then I think I'm in fine shape.
I can say without hesitation that the best triggers are on my Colts. The worst is on my Ruger. Even so, they are all better than the double action on any automatic I own save for an ASAI One Pro.
