Super Bladk Eagle Problems!

[Larryjk]

A fellow brought his Super Bladk Eagle to me and said it wasn't firing everytime he pulled the trigger. I disassembled the gun and pulled the trigger group from the frame. I disassembled the trigger group for a good cleaning but didn't find any problems. I disassembled the bolt assembly and gave it a good cleaning and didn't find any problems. I reassembled the gun and took it out for test firing. It didn't fire each time. The hammer cocked correctly but fell very lightly (watching it through the slot for the operating handle). No reason, the spring was just fine when I checked it. The shells that were in the chamber when it refused don't have any mark on the primer. I am sittin here, scratching my head. Any one have a clue?
