Gorkey, I never put "rubber" grips on a single action, it counters thier best feature, the ability to roll, which in turn helps to absorb the recoil. The amount of roll will depend on the load, and as mentioned, you can run loads through a Ruger that will leave a 29 in small pieces in the dirt, even with the improved lockwork. As for whether this will reduce the control of the gun, it kind of depends on what you expect from a quick second shot. In spite of TV, you will never be as fast with a SA as you are with a DA, there's only a couple of people on the planet who are. With practice, I don't find it too onerous, and can manage a second shot in roughly a second, give or take. The barrel length will play into the roll of the revolver as well, longer barrels have more weight, and don't flip as quick or as much. Heavier bullets ditto, 240 gr loads don't roll up near as much as 320's. FWIW - dan
