Before I start a forensic dissection on the gun, I thought I'd ask opinions....I have an ejector gun that occasionally will hang-up the ejector bar on one of the firing pins when trying to open the gun. The firing pins appear to be loose in their housings and will freely fall forward and stand proud of the face of the breach plate. Is this indicating broken pins or is that normal? Not sure I've ever seen one do this. Both triggers seem to fire (on snap caps).
