Mine had Pachmeyer rubber grips on it when I bought it from my brother. Fortunately, he kept the original wood grips. I cannot believe how valuable those wood grips have become - probably because most folks took them off after the first time them shot the gun. I don't know what Colt was thinking. They are truly terrible. The checkering is proud, rather than recessed like in S&W grips. It's like holding onto a cheese grater.
I like the recessed checkering on S&W target stocks.
But, even then, I've switched them out to smooth wood. The M29 wears Eagle grips, which have a palm swell that I like. The M19 has another set of Herretts, custom made to my hand. They have a tracing of my hand and some measurements on file, so all I have to do is give them a holler and they can make grips for anything I want.
