Just wanted to throw out there that I've begun work on a overarm CNC program to checker my grips to the same pattern, angle, and slightly greater depth as that in the Rohrbaugh triple pennant emblem already in the new C10 grips. It will surround the emblem without altering it, using a border, and will cover most of the flat surface both grip faces,and will also be edge-bordered. I'm thinking this work will improve handling and ease of draw (particularly when the palms get humid) without detrimentally increasing holster or pocket friction. I can't bring myself to put stickyback all over the gun or "combat" the grips, and I agree they could be....well... 'grippier'.
I'm leaving the frame alone. My theory is that near-full checkering of the grips will add more than enough extra surface area without the need to mess with the metal.
If the process works I'll be happy to offer it to anyone interested - in exchange for home-cooked food, ammo, really good tequila, or just enough hard cash to make it worth my while. I'll post pics of the completed grips (unless I butcher them, in which case I'll be hunting for some replacement grips soon). Moderators, please feel free to move this post to the classified section if it's deluged with requests...`:~>
If not, or if I'm reinventing the wheel (again!), someone please give me a backhand and tell me who's already doing this... Thanks!
