Didn't vote in your pole because none of your answers actually fit.
I can and generally do take apart Smith & Wesson revolvers and have done so since buying my first one in 1973. I also frequently took apart the Ruger single action revolvers I've owned, but they were all 3-screw models. When I was really into black powder cartridge shooting (for close to 10 years) I routinely took apart my Colt SAAs, down to the last possible screw for thorough cleaning. Even taken a few of the above guns apart for repairs or tuning although I don't consider myself any kind of gun smith.
