Recently, I shared an old Army issue 1911 I'd acquired. I immediately put the original grips away, since they're rather fragile. Since then, I've been looking for the right grips to serve as substitutes. I went through several I already had, as well as a new set from Wood Caliber. None of them looked right. Wrong color, incorrect design elements, or simply just too nice.
I happened to notice Tisas sells grips on their website, in both light and dark walnut. I decided I couldn't lose at $20 and ordered a pair of the dark walnut. I applied a coat of stain (since Tisas kindly doesn't put any finish on them) to give them just the right reddish tint, that vintage US military wood always has and bam, perfect.
