Delivering the same world-class features as the 5-inch model, the 2K11 Pro features a 4.25" fluted, crowned barrel and rock-solid external extractor. Kimber's GT Trigger delivers short travel, zero creep and crisp break between 3.0 and 4.0 lbs. The tool-less guide rod is a patent pending Kimber design that delivers ease of cleaning and disassembly. Kimber's engineers pushed the limits with our enhanced sub-frame, for superior magazine fit and control. Grip module options include aluminum at a fraction of the competition's price. The stainless-steel slide features a disconnector ramp for smoother operation. The accessory rail supports lights and lasers while the slide is equipped with TAG Custom FiberLok 2 front sights and comes standard with a C&H Precision optics plate for the Trijicon RMR family.
