The ERGO XTR grip panels are aggressively textured hard rubber grip panels for the 1911. The grips fit the government and commander size frames and have a square bottom. The aggressive texture provides a solid grip in any condition, but is not as aggressive as grips with sand texture. These panels are also low profile and reduce the grip size over standard, mil-spec panels.
