If you do a bit of research on milling the rail off firearms you will likely learn 1. It is not a new idea
2. It only takes someone with the skill and quality equipment to do it
Personally, I have been lurking, looking, for a couple years for a beat up S or T 120 at a very low price to do that very thing to. My bedside howitzer sized .45 is my only railed pistol. I chose it because with its heft and size that rail only adds panache to a formidable club. I keep a flashlight right next to it....I can?t shoot worth squat with the lasers I have tried....not a rail guy. They sure sell plenty of widgets to mount on a rail. I am old enough to remember curb feelers, lake pipes and blue dots.
