Obviously, another 'gun shop commando' has surfaced...
The 'only' thing I've ever seen on period weapons was lightly-done engraving on revolvers used mostly during the Civil War.
No one wandered the 'real' Old West modifying his revolver for better gunfighting - to the guys who really carried, their sidearm was a tool.
Stippling per-se - was done on the M1911/M1911A1 autos being used in the National Matches, after they discovered that glued-on ping-pong paddle material would erode.
They even tried flint paper held in place underneath the grips - but oils defeated those.
If one wants a better grip - look at your open palm, and see how the creases align.
Looks pretty much like those 'Longhorn' grips, doesn't it?
That style, and the style that has a raised surface that fits into the hollow of your hand, will greatly help with aligning your grip, and/or absorbing felt recoil.
Vaya,
Scouts Out!
