I took some sandpaper to my Glock 23 RTF2. It’s not that the texture was rough on my hands… On the contrary, I liked the texture. Unfortunately my clothes didn’t like it. Underarmor brand shirts would snag badly. Work shirts.  Sweatshirts too. And if I didn’t wear a t shirt under it, it would savage my side. So I sanded the flats. The front and back straps remain RTF2 textured. Gripping the gun is pretty much unchanged. The pistol locks into the hand rock solid, as usual. I may try some stippling some time, but I’m in no rush.
