I have a flatgate Single-Six (ser. no. 8xxx) that I bought at a reasonable price several years ago. It has the sort of wear you would expect of a gun that’s over 50 years old – worn finish, a few chips in the gripframe anodizing, etc. but overall is in good shape and shoots well. While I certainly like the gun and appreciate the historical significance of the old flatgates, I’ve seen a few examples of customized Single-Sixes by some of the well-known pistolsmiths and I’m intrigued enough to consider something similar for mine. Among the things I'm considering is leaving the caliber as is but shortening the barrel to 4 inches and installing a traditional dovetail-style front sight, a blackpowder cylinder chamfer, color case hardening and refinishing. I would preserve the unique features of the gun like the flat loading gate and the serrated ejector rod button but before considering this much further I’d like to verify through the experts here that I’m not unknowingly committing an act of sacrilege by modifying this 4-digit gun. While it's a nice gun, I don't think it's what one would consider particularly collectible - it's a nice shooter. I simply think it would be fun to create something unique while preserving the heritage of the old flatgate. Your input would be appreciated - thanks.
