I have made some grips for myself. I have also done a FEW for others. In general,, it takes time as I like to take my time & do it right. I have a real job,,, so it's strictly a hobby for an occasional project. I got started as I needed some grips for a few guns with that danged infernal,,, eeerrr,,, internal lock. I didn't like the factory plastic,, so,,, I chose to make my own. Trial & error,,, combined with a bit of research has allowed me to make some that turned out pretty good.
