I did a tread tape modification on my old Ruger P-series pistol a couple of weeks ago. I took it out & shot it Thursday. It had been a while since I last shot it. I did not shoot it as well as I would have liked. I suspect part of that is just that I don't get to shoot enough. I do like the tape on the grips, front strap & backstrap though. It feels much better than either the stock grips or the hogue finger groove grips I had on it. The ergonomics of the 669 I got to shoot just worked for me. It was easy to shoot well. I need to get out & shoot more.
