Patient: Ruger Security 6 in .357. Early 150XXX serial number prefix. Sat in buddies closet for a good many years because he couldn't fire it.
Symptom: The trigger on this Ruger could only be pulled through to hammer release about 1 out of 10 times. You had to hold it in your hand and literally throw the revolver forward then pull the trigger (or you could hold it pointing down and shake it). Otherwise, the trigger (and hammer during single action) would freeze about 90% of the time when trying to fire.
Diagnosis: (here's where a Sec.6 expert/gunsmith can chime in) It looks like the pawl plunger is stuck in the trigger. From Numrich diagrams, I see that the pawl plunger should have a spring behind it. To me, that says the pawl plunger should free float in the trigger and put pressure on the pawl. Since the plunger is stuck and not keeping the pawl pushed forward, the pawl is able to fall back and get stuck up in the firing mechanism (??), thus the freezing trigger.
Am I correct here? Should the pawl plunger move in and out of that hole and put pressure on the pawl?
Any help appreciated,
