I had a chain fire with my first black powder revolver and it is not something I would care to repeat... In fact my first revolver was an 1851 Navy Colt (reproduction of course) and the chain fire resulted in stretching the frame of the revolver a little. This stretched frame became apparent every time you would shoot, because a small amount of the ball would be shaved and splatter all over the place when you shot it. I took it to a gun smith and that's the first thing he asked was, did you have a chain fire? He cut the frame back but I never trusted the revolver again, and sold it to a person that wanted a wall hanger.

That was another reason why I got the 1858 New Army model with the top strap. They are just a stronger made revolver IMO.
