I discovered after a closer inspection of the safety mechanisum that there was a brown sludg so I removed the role pin to discover a mess of brown rusty goop and a spot on the actuator that appeared to be contacting the frame. Cleaned everything real good polished with dremel and lubed. Now she goes bang once again. 1st rule of gunsmithing make sure all is clean lubed and working properly. Thanks to all for the replys.
