Have any pics of the ones you have done?its easy and quick to if you have some metal shaping expereince. I have done it on numerous PPK s and TPHs to make the factory lines more correct.
the Fort Smith "fangs" show in in your picture do indeed look atrocius
Kind of moot now as I found a German made one right after I started this thread. I am waiting for the state to approve my permits (yes in my state you have to get a separate permit for EACH pistol you buy).
I have done tons of steel, aluminum & copper metal stuff since I was a kid. I am no stranger to a vise & a mill bastard . Swiss needle files are your friend .
My Dad taught me how to do it. Heck even in his 80s he was still doing stuff till the COPD did him in this past Christmas.
