I can't see the pics (some are blocked at work) but my pin is not sticky. When I pull it out to its full length (or it just falls all the way out because I'm tilting the rifle back [muzzle up]), there is no spring resistance when I go to push it back towards the breech; it basically free floats between being fully protruded and just shy of being flush with the breech. I disassembled the firing pin assembly last night to make sure that it was clean. It was, but I cleaned it anyway just to be sure. All channels are clear, no carbon build up, etc.

I basically feel like the spring isn't long enough for the firing pin. It was a tiny, weak little thing.
