When I pull the trigger and restrain the hammer with my thumb I can see the transfer bar raise up some but you`re right, after the hammer travels forward some more I can`t tell if the transfer bar raises to cover more of the firing pin or not.
I also have a question about the value of the piece.It`s a 6 1/2 inch with a little wear of the blueing around the muzzle and the top of the front sight.Otherwise all the blueing is in fine shape.
S/N is 32-43xxx.
I picked it up for what I thought was a bargain price of $175.
