For me the G43’s texture is not very aggressive and is almost slippery. For this reason I purchased and applied a Talon grips for both my G42 and G43. The Talon grips are an adhesive rubberized, precut, and sized tape that applies in minutes.
The difference is amazing. I no longer feel like the gun can slip out of my hand if they are sweaty or wet. The Talon grips have lasted over a year without any signs of wearing off or peeling. I did follow the directions and used a heat gun to help the adhesive adhere to the polymer as I used hand pressure to secure it tightly to the frame.
