Luger Carbine Front Sight Question

Shoot...Either of those shapes, I don't have a tool to cut grooves in a ramp...Steps maybe, but not grooves...If I had a shaper, that would be ideal...But I don't...

Why not grind a keyway cutter to the dimension you want?

I have a 60º V-shaped keyway cutter, but I don't have any way to clamp the [integral] sight base/ramp to mill it...[pic]...

I also have squared-edge slitting saws if I wanted a thin square serrated bottom series of grooves, but same clamping problem...

I've held off milling the ramp angle until I know how I'll serrate it...

... ...

I suppose I could turn the ramp instead of milling it...and turn/serrate it with a threading bit...Like the Finnish Luger barrels...

Nah...

Several years ago [70's?...80's?] I did a 6" 9mm barrel with pressed in 3/8" dovetailed front sight (too wide but only cutter I had) and milled 'steps' in the back of the sight & ramp...Something like .020" up, .030" forward...Repeat...But that won't work on a long ramp...

Back then I had a decent mill [Bridgeport 2J] and it was easy...
