JB, I've had great results, just polishing everything, and rounding the trigger to take off the sharp edges, I'm a Smithy who's favorite revolvers are S&W, but have had very good results with just polishing everything on a Ruger, I use cratex cylinders, and a buffing wheel to do this. You can use a dremel and felt wheels with buffing compound to accomplish the same thing with patience. Stay away from the single action sear unless your willing to fail, and carry through, with either more research or sending it to somebody for correction. I don't mess with coil spring ignition systems, that means I don't use spring kits, or shorten springs for a lighter pull, you either can't cut enough off for reliable ignition, and still feel a difference, or the spring kits, show a big difference, and won't reliably give good double action ignition.
