Jimmy, who has a lot of experience making and painting rifle stocks, wanted a special look for his 1911 grips. As you can see here, he went with a green paint job and some grip tape. The paint he used is Aluma-Hide II from Brownells. He chose it because it comes in a can, as opposed to DuraKote and Cerakote as they require mixing and a sprayer or air brush.
If you have a story of a grip you've painted, please share it (and a photo) below.
David had a similar plan for his Buckmark. Starting with a black PLA grip, he did some final fitting to his hand with round file and sandpaper and then applied Rust-oleum textured spraypaint.
It doesn't matter if you're still trying to find the black, or have been a High Master for so long you look at a 9 as a tragic mistake, you're probably never going to be done working on your grips.
