fez, Rugers are the number one gun in cowboy action shooting. These folks do not fan but thumb their guns for speed. You have to remember, the hammer will only go so far back and forth. The hammer spring dictates the fail of the hammer, all you are doing is bringging the hammer back in a fast motion. If you had a Colt this would be a problem but you have a Ruger.The reason is the durability of the Ruger verses all other Six Guns. Elmer Kieth stated he had never seen one worn out or talked to a gunsmith that had ever found a wore out Ruger. That is why we LOVE them, they are the work gun of mankind, indestructable and mighty, dependable to the end. I walked out in my yard the other day with my little Stainless Bearcat with Aquillia Humingbirds and fanned six rounds into my wifes new plastic planter. I almost had an experiance. She has not seen these results yet but, hey I am the utimate Fanner Fifty handgunner from 1959. If I tear up my Rugers, I have a heck of a good gunsmith or if it is something I can't replace, hell, I'll buy a new one for a few hundred bucks. So be careful and fan your ass off.
