My first try at 5-stand was stalled today when my gun decided not to play nice. I just now pulled the stock off and the fault was easy to find, see the photo below. The pin (dowel rod?) that you see sticking up in the air is supposed to be flush with either side of the trigger mechanism just below the main spring. It is a loose fit and I see nothing missing that would otherwise keep it from migrating out of place. I pushed it back in place with my finger and I was instantly back in business. Is there a standard practice for re-creating a proper friction fit for a hardened, solid pin like this? There is no axial pressure on the pin to force it to move; I assume it vibrated out of position. Ideas? Maybe anneal, slightly bend, re-harden and tap in place?
