Because of a hand injury, or arthritis, my R9S inflicts severe disabling pain on my shooting hand.
One of the Super members here sent me some tape, which I put on the front and back of the handle. It has a coarse surface somewhat like sandpaper.
The result was astonishing. The recoil was completely under control. There was not the slightest hint of pain.
If you have any discomfort with the R9S, I urge you to use the tape. It makes the pistol a joy to shoot. You will be very pleased with the result.
Today I tried Ranger 147gr, Magsafe 60gr, Federal 124gr, and WWB USA 115gr. All worked perfectly.
My new favorite is Magsafe 60gr Defender, which seemed especially mild.
