Monolithic frame is made from aerospace-grade, 7000 series aluminum. Patented friction reducing cam is a next generation design in fire control systems that results in a smooth, non-stacking trigger pull. Patented polymer fire control housing holds all the fire control components in their proper dimensional relationships, reduces weight significantly and helps reduce recoil. High-strength stainless steel cylinder is extensively fluted (reducing weight) and features a PVD finish for excellent durability. Allows a variety of grip styles to be installed, leaving ample room for recoil cushioning. Includes a Hogue Tamer grip, which is highly effective at reducing felt recoil.Replaceable, pinned ramp front sight with white bar.
