These Kensight Sharkskin 1911 Grip Panels are constructed from durable DuPont PA66 polymer, making them impervious to the elements and resistant to most solvents and oils. They feature an aggressive, nodular texturing that closely resembles sharkskin in both feel and appearance, greatly enhancing the shooter's grasp on the pistol during recoil. These grips feature a square bottom with a slight taper, and fit both 1911 Government and Commander sized frames.
