broken shotgun, not sure whats wrong...
A friend of mine picked up a new shotgun, and gave me his old broken one. it's a no name brand, a "ultra 87" and won't shoot. When it's fired, theres a click, but nothing. when you eject the round, there is a little puff of smoke, but the round is unfired.
The only damage i can see is the hammer is chipped and theres a little damage on the firing pin.
Could this be the problem and how can I fix this ? I would like to keep this shotgun. I am thinking of trying to find a replacement hammer, but if that doesn't fix it, I dont know what to do.
heres a photos.
