Anyone know which generation of Colt SAA grips fit the Uberti Cattleman / El Patron? I have the Uberti on order (which comes with one piece checkered wood grips), and am considering either a set of aftermarket Colt SAA black rubber eagle grips or faux Ivory/ stag. Anybody know of something I can put on the gun that doesn't require drilling into the gun frame for the 2nd pin hole? Which generation Colt grip fits the Uberti?
