If you haven't gathered, I'm going back through some old projects recently.
I have had this H&R Self Loader for a couple of years and this issue existed when I purchased it. The symptoms I am experiencing is that the slide does not want to retract all of the way. I have isolated this to the firing pin spring and it's guide rod. If the firing pin spring and Rod are removed the slide will retract all the way. The firing pin spring was found bent in its track. I suspect I will need to replace the spring. Fortunately they are available.
I have attached one of the two diagrams I have for this pistol. This diagram shows the guide spring head entering into the rear of the firing pin. The other diagram I have shows the guide spring head resting in a recess in the slide return block. Noted as part number 11 on the diagram. For your information, the diagram indicates that the firing pin, spring, rod are above the recoil spring. In fact this is just the way they drew the diagram. The Recoil spring is actually above the firing pin and it's spring and Rod.
I think to solve this one, I will need someone who is either well-versed in this particular model, not very likely, or someone who has one that is willing to open it up and help guide me through how this spring and pin are arranged. I have tried every combination I can think of and the spring steel bends and prevents the slide from retracting all of the way.
I have seen one video of the disassembly of this type of pistol and it appears, at least on that pistol, that the firing pin spring guide rod is attached to the slide return block. It does not appear that it was ever welded or soldered in place. But it does not fit tightly in the recessed in the slide return block and will fall out if I place it there. The firing pin spring guide rod is a part that is shown with its own part number separate from the slide return block. So I assume it is either loose fit or soldered to hold it in place. And I guess that is the real question.
