Things are different with single action revolvers. The first thing is to compare apples to apples. There are three basic types of Ruger single actions. The old Colt clone 3-screw without the transfer bar safety, the modern transfer bar safety gargantuan models and the newer XR3-style with a old style size and grip with a transfer bar safety. The real difference is in the absence or presence of a transfer bar safety. The next major difference is in the gate interlock or absence of said item. This feature was to only allow the revolvers to be loaded when the gate was open, blocking the accidental cocking of the hammer or allowing the action to function by pulling the hammer back and letting it fall forward intentionally. It also only allowed a one direction ONLY movement of the cylinder. It was not well liked. Ruger listened and realised that a large number of their revolvers were being converted anyway. The new Ruger Vaquero was born. The issue is strength. Rugers have been known to take pressures that would turn a Colt or Cotl clone into a grenade. The new Rugers do NOT have that ability/strength. That is the short story on Rugers. The clones varied greatly in quality and had soft metals used in them, they wore out fast or broke. CAS or cowboy action shooting has helped improve the quality and durability. CAS shooters helped put two poor quality and questionable companies out of business. ASM or Armi San Marcos are known to be POJ and poor quality single actions. Before this was known though, EMF-IAR, Traditions, KBI-Liberty, Cimmaron and others imported and sold them. A company called AWA or American Western Arms even sent US steel to Italy for ASM to make their Peacekeepers and Longhorns out of. Bad quality. ASM and AWA went under. I do NOT suggest buying any ASM single action in Colt or S&W clone form. Now comes the better manufacturers, Uberti, S&W, Beretta, Pietta, USFA and technically, Colt. Colt had Armscor in the PI produce a Ruger clone. That is the even shorter story on clones. Colt has made single action revolvers long enough to know how to do it right, they did build some dogs back in the day. The Taurus Gaucho model is one of the best clones that I have ever held or pulled a trigger on. It needs little to be an excellent competition revolver. The loading gates don't allow the freespin of the cylinders even in the Rugers. They rotate in one direction only unless converted. A halfcock is needed for Colts and clones to release the cylinder, then the gate allows loading. I don't suggest freespinning a cylnder myself. All Rugers, Colts, S&Ws and clones are built better now than they ever have been. The quality is up across the board. I suggest CAS-City for knowledge, experience and good advice on generic single actions. TFL has a good base in the BP forum. The best place to begin though is with the owners manual of the model(s) you are interested in.
