had a fun weekend shooting tons of ammo and targets. however we encountered one mishap. my revolver busted. the little parts came out of the hammer area. my brother was using it. fired 3 rounds then it locked up. the cylnder would not budge. it took him pushing the pin and pulling the rod and me working the hammer,cylinder, and trigger to get the cylinder to release. after release the little tiny hook piece fell into my hand. the other three came out apon being home. so my questions? what are the peices? what are the availabilty of the replacement parts? what are the costs of parts? is this something i can do? should i scrap the revolver?
