Bob:
Well, not really.
The hammer will fall forward, but will not go far enough to allow the firing pin to extend through the frame so as to strike the primer. These, like the originals, have a rebounding hammer, so in the "at rest" position the pin does not protrude through the frame. On firing from full cock, however, the hammer/pin is supposed to travel far enough to strike the shell's primer and then return slightly backwards safely into the frame.
The problem with both of mine was as I just described. The solution, as I posted earlier, was simple removal of the hammer block which, of course, cured the problem.
I was just wondering if you had found the same situation with yours.
