Just acquired my first 1st gen Colt SAA; a Bisley manufactured in 1908. The grips are a somewhat ill fitting rosewood. So I ordered replica OEM Bisley grips from TripleK, and I could not install them because of gaps and overlaps at the top of the grip strap. Trying to research any grip variations but nothing so far. Anyone have insight into original Colt Bisley grips and any variations and most importantly, where I can buy well fitting grips?
