Try a set of one-piece 'faux' Ivories with the device on the right panel only - like the originals.
I have a set of 'Mexican Eagle' on a 7 1/2" Colt, and once I re-cut the entire design with a single-line checkering tool, they look great.
The up-side is that the device sits directly in the hollow of your shooting hand - acting as a stabilizer in heavy recoil - and the grips have a slightly greater weight - additionally giving a greater sense of balance for an instinctive shot.
Good Luck!
