Our Roughneck Browning Hi Power Grips have aggressive checkering that looks great and really feels good in your hands. They are made from Phenolic G10. G10 is only 1/2 the weight of aluminum but nearly as strong with a grippier texture. G10 won't crack or shatter, like the cheaper polymer and acrylic grips are known to do. The color is dyed into the material, so scratches aren't an issue. G10 grips will last a life time under normal use.
