Anyone have a problem with theirs?  I was dry firing one and all of a sudden it seized up, TERMINALLY.  After a few tens of minutes swearing and struggling to get it apart, I pull of the side plate to see, much to my surprise, THE FIRING PIN stuck in front of the hammer and no sign of the FP retaining pin but metal flakes concentrated in the area where it should have been

I can't find the missing pin, so I can only assume it disintegrated or something.  Revolver works alright otherwise now, but Midway and Brownells are both out of that part.  Anyone know where to get one, or at least the specs so I can make another one in the machine shop?  

Thanks,

Made my own out of a piece of rod I had lying around of the correct diameter.  Seems like it's much more durable than the factory setup.  Got to OPTEST it first but I think it'll do nicely.
