This is a Kimber grip safety featuring a tactical bump. The high sweep design gets your hand deep into the gun reducing felt recoil because of better alignment of the centerline of the bore with the axis of your forearm. It also improves your natural pointing ability leading to better accuracy. It is compatible with all Kimber models as well as many other 1911 style pistols. Some fitting may be required.FeaturesIncreased comfortImproved weapon control High sweep design
