Does the extractor rod walk out?

My first thought

If the firing pin is piercing the primer chech the main spring screw under the grip. Take the grips off and if there’s an adjusting screw - back it out a quarter turn. It puts pressure on the flat spring, I have a Model 27 which suffered from light strikes, tightened the screw and that corrected the problem.

part # 55 is the hammer adjustment screw , back it off a quarter turn or so.

This is a usual suspect , if the problem is failing to set off primer . But wouldn't cause the piercing and embedding in the primer .


If the firing pin is piercing And Sticking , it's a problem with the firing pin . Broken , chipped , a burr , something .
