Yes it is the Millennium PT145 model, I forgot to include that. I have seen firing pin smear before, but not to the extent that this gun has. I was maybe going to take it apart, and see if the pin is dragging on anything, or if there may be a burr or something. I know a little bit of smear doesn't usually matter much, but when it reaches near the edge of the primer, I figure that can't be very good for the firing pin. I kind of looked on line to see if anyone made an extra power firing pin spring for it, but it appears that no one does. I wonder if any of Taurus's other .45's have this problem. Also the loads I was shooting were a mild ball load, and I think the smear will be worse with hotter loads.
