This past week I was shooting my 1982 Ruger .45 Colt BHK..all of a sudden I couldn't cock the revolver--seems that something broke inside of it. I opened the loading gate and removed the cylinder--a tiny part fell to the ground. I took it apart and soon found the issue---the XRN-41 Hammer Plunger tip broke off. I emailed Ruger and they promptly responded that they send me a replacement. Was wondering if anybody else had this happen. I shoot mainly .45 ACPs in this pistol and never any "hot" loads. Funny this pin would break on this caliber and not in the .357 BHK and the .44 SBHK---both of which I shoot much more often.
