Fingertip Gripz includes: Two tactile finger grips (1"x 5/8") with self adhesive backing, plus an alcohol prep pad to clean the surface prior to install. This product was designed to help manage recoil, and assist in establishing fingertip muscle memory when drawing a firearm. This muscle memory is important in maintaining firing consistency as well as safely keeping your finger off of the trigger. Fingertip Gripz is also great for those who tend to get sweaty hands when firing, which can improve accuracy. The Gripz can be used on virtually all handguns, as well as a wide variety of rifles and other firearms.
