Not a SUPER but I did my REDHAWK the "Bubba" way (according to grobin) with hacksaw and files. IT'S NOT THE TOOLS YOU USE, IT'S YOUR SKILL:
I shortened from 5 1/2" to 4 1/2". (removed instruction manual but left Ruger address and Reg mark in circle):
It wasn't two weeks later that I saw my first Ruger made 4.2" with its plain pinned front sight! So I wasn't disappointed that I cut mine because I re-used original sight with replaceable blades. Plus I prefer the 4 ½" length over the 4.2":
This view shows seams. Because the sight was longer than the 1" of barrel removed, I couldn't cut out the front sight base deep enough without cutting into the bore of the first ½" of remaining barrel. So had to use a spacer for proper sight height. You won't have that problem if you're starting with a 7 1/2" barrel or shortening to 4".
Blade removed to show hidden attachment screws; two titanium 2-56 fillister head torx screws:
