.41 Magnum Man
Sir: Visit 'Old Fluffs' thought. Mill off flush the sight. Mill the slot, ie dovetail, square, or how-ever a Machinist would see it. {being the machinist that you are] Remember the Heat in Milling. Silver Solider will fail.
The Square Post that you have drawn.
Question that for yourself? I'm not sure why, or what you are visualizing?
My interpretation of "Ramped" sights
1. Less sharp angle [getting in and out of holster,pocket, something]
2. More/Less to file to shooting 'FIT'. [heavy bullets high, lighter bullets low
3. Looks better.
4. Single post? [maybe weaker, ie bending? maybe hang more,
I personally can see many/multiples, advantages to 'Old Fluffs' ideas
Now excuse me sir if I misunderstood your MACHINIST History.
Slot it and Pin it.
Make additional heights to assist the bullet
What Fun to have available tools for this application.
Good Luck: Craig
