Parabola, very nice gun. Those self acting ejectors are nice, and they work until there is excessive wear or if the the geometry of the sear noses is changed. The old gunsmith rule on these self acting ejector mechanisms is that it’s best not to alter the trigger pulls on these FP actions. They were adjusted and timed at the factory and should remain how they were if possible. The sear nose and tumbler bent are critical in keeping the mechanism in time.
My G-guns do not have the bolt release stud in the action that your gun has. I’m going to post a picture of what the internals on one of these self acting ejector mechanisms looks like. They are actually very simple. There are no separate “cocking dogs” in this action, the tumbler (hammer) and cocking limbs are all one piece. Actually a very simple & very robust action, very few parts, the critical timing of the action being most important to keeping the guns mechanism healthy and working correctly.
