Neither one of them knows their ass from a hole in the ground
much less anything about guns, much less about Stars. What I did was cut a shalllow slot into the rear of the slide, beyond what had to be done to fit the 1911 firing pin stop. I reduced the OD and thickness of a Dremel cutoff disk's mandrel screw head as much as I could get away with. Clamped the Star slide upside down and horizontal in the vise, and took about an hour, with low rpms, to fit the 1911 pin stop. I had to reduce the size of the pin stop, too. Then I cut the 1911 firing pin to fit inside the Star slide, and that was that. This was on a Pony 380. With the BM, you don't have to cut things down as much.
