I have a SBH with a Bisley grip, the other day I was shooting off the bench the ejector housing screw broke off and everything went flying. Found all the parts and even got the broken screw out of the barrel. Look at everything, it looked allright accept the ejector housing was missing. So I continue shooting my group, shot the fifth round and couldn't remember if I had five or six rounds in. So I aimed and shot a empty cylinder, went to unload the cylinder would not turn. The firing pin was sticking out hitting the case. Got it apart, clean it all up tried it at dry firing stuck firing pin. It works on loaded rounds fine, but fired cases it sticks. The parts from Ruger are inexpensive, are they difficult to install. As I'm getting a new housing screw from them I thought I get the firing pin and spring. By the way anyone ever have the same illness? Thanks
