Hogue Extreme series grips are machined from Aerospace grade 6061 T6 aluminum, titanium or old world Damascus steel. Extreme grips are available for most semi-auto pistols that Hogue currently makes and are carefully engineered and sized for the ultimate in fit, form and function. The strength of the materials allow for the thinnest possible grips on large double-stack autos such as SIG pistols. Extreme grips are precision machined from solid billet stock to exacting specifications and are designed for a lifetime of use. Aluminum grips are hard Type III anodized and available in clear, black, red, blue and green. Titanium and Damascus steel are polished to a high luster that accentuates the natural characteristics of the material.
