Most of what I said on the Ruger Gunsmithing sub-forum goes for the Colt Single Action also. Its easily taken apart for work amd parts replacement.
One note about Colts:
It is a popular thing to mill out the top strap and fit a Smith & Wesson rear sight, on both Colts and Ruger Vaqueros. My .357 Single Army was set up in this way.
Several years ago I was shooting at the local range when my groups suddenly began to rise. Shots were soon over a foot high at twenty-five yards. Puzzled, I tried to load five more, only to find the cylinder difficult to rotate. Examining the gun, the barrel was sloped downward at a noticible angle, enough that the rear of the cylinder was binding on the topstrap. I though I had reduced this gun to a parts gun, but took it to Bob Mason, Memphis gunsmith, who was able to realign the frame for me.
As a result of this, I no longer recommend such sight installations. These loads were my normal .357 Magnum handloads, not heavy nor heavy bullet handloads, using the 140gr. Speer JHP bullet.
