If your intedtions are to actually use this gun, in a tactical or carry manner then I have been real pleased with the ...........
VZ Grips. Micarta and G-10. I currently us the VZ "Operator" G-10's on two of my 1911's. Nice grip serrations/checkering that provide a positive grip with both bare hands and gloves. Impervious to oils and other water etc.
Night Hawk Custom uses these grips on many of thier high end models.
I highly rec' them over the aformentioned grips.
