Last I knew Brownell's offered thin but sharply "checkered" metal wrap-around frontstrap covers for 1911s in blue and silver. The edges tucked under the stocks and locked into the frame cuts there.
I put a blued one on an early milled 1911 frame that looked (and works) fine. The cast frame on a Springfield Armory pistol is just a little bigger; the ends do not fold over into the cut as nicely but I mixed up a little JB weld, glopped it in, and it has held up ok. In both cases they look right, give a nice secure grip, and are removable with no alterations to the gun.
Have also used the skateboard tape on BHPs and similar.
NO idea why manufacturers don't do it on ALL pistols. It should have been done way back in 1911!
