Oh glee! After returning from work irate and completely pissed off I managed to fix my gun!
So playing around I realised the gun would no longer go into safe anymore. This let to exploring beneath the safety selector with a flashlight and some toothpicks. I eventually dug out part #52 from way down in there (looks like it wasn't lost after all).
After deforming the end of the pin a little so it stays in the hammer assembly better I reinserted it. Reassembled and gun is shooting just fine again.
I made sure to not sit there and try firing my gun repeatedly while it was in this 'broken' condition. Thereby hopefully avoiding any unnecssary wear on any other parts. Just to play it safe though I ordered some extra internal bits and a replacement set for parts #50, #51 and #52 so when the time comes I can rebuild this thing.
Yay for not being useless!
