Ivory grips sound good on your police model. Post a picture if you get a chance, or e-mail me one at: chiefboring@military.com
Colt 1851 Navies were a popular presentation piece to WTBS officers, and always looked good with ivory grips. I once passed up a chance to buy an 1873 SAA, engraved, nickeled, with one piece ivory grips. Every time I see current prices, I kick myself. Oh well, looking where you've been doesn't help much. Gunny, stay safe. Semper Fi, Anchors Aweigh, and fair winds and following seas. Stan
