My Redhawk has a very annoying problem. After 15 to 20 rounds, either the hand or cylinder starts hanging up. I shoot it mostly SA, but when it starts acting up, it won't c$ck properly. I have to help the cylinder rotate with my left hand, while c$cking the hammer with my right. After a cool-down and cleaning, problem is gone. Does anybody have experience with this? It is brand new, and has always done this. I know sending it to Ruger is an option, but if it is something simple, I will try to fix it myself.
