Yep, I picked up a roll of non slip tape for stairs/ladders at Lowes. It's heavy duty and this stuff does not move once on the weapon. All my seams are completely flat against the the frame. Since the stuff I used is pretty thick I had to get creative on how I did my backstrap (see above) due to curves, hump, etc.
What I did was cut a piece of paper then held it on the my grip, I used my finger nail to trace around the seams which gave me the general outline of the piece I was making. Then I took that and traced it onto the grip tape, cut it out and fine tuned from there.
Yep...when I made my "Gen 4 Stipple example" thread, I wanted to see what a more permanent solution looked like. Most people couldn't understand because the Gen 4 is this "new" and "improved" texture. I'll tell you this....those little flat squares on the grip don't do squat when your hands sweat. This grip tape makes the weapon stick like glue. People who shoot for a living will appreciate the improvement.
