"smoothing" a sig p238?

[dreamweaver]

the sig has a width of 1.11" and a very blocky slide with alot of sharp edges.
the slide is stainless. i want to radius all the edges on the slide and smooth the sights as well.
I'm guessing doing it by hand would be the best, but was wondering about machining it. could a metal cutting bit be mounted in a shaper/router table to get a finish cut?
I'm planning a 3/16" radius
thanks!

Ive done a few colt mustangs and ponys. Just using files and some sand paper to smooth out the file marks. Bead blasted and duracoat You can go with a light dehorn or really slim it down including the slide release and mag release. All up to the craftsman.

thanks jim,
do you scribe lines for width of the radius and file to the line, or just eye ball it?
I actually like blasting with aluminum oxide and finish with cerama-coat, but it all looks the same in the end.

you can buy concave radius mill bits like

but those are usually for bead details, so you need to put it on a lathe first to trim it from a 180 degree to something like a 90 degree edge cutting tool. Combine that with trying to align the gun just right on the mill table, I think you get better results doing it by hand.
