I have looked for thinner grips for a mid 1980s Redhawk, but none seem available. They have also changed the grip locator, such that the new grip locator does not fit in older Redhawks. The new Houge grip goes with the new grip locator and will not fit the old. The new grip locator will not fit my gun.
All the grips I have tried are LARGER than the factory grip, NOT smaller.
One of these days Im going to get out some sandpaper and start whittling down those grips.
