Browning Buck Mark rimfire pistols lead the industry in quality, reliability, accuracy and variety. Every Buck Mark starts out as a solid piece of aircraft-grade 7075 aluminum alloy, and then is CNC machined to exacting tolerances. The finger grooves, laser stippling and stylish wave patterns combine to form an Ergonomic Interactive Surface (EIS) that puts your hand in the same place on the grip for every shot, resulting in more instinctual shooting and improved accuracy. The textured surfaces are comfortable and secure in any condition, while the narrow profile makes them perfect for all hand sizes. Features alloy receiver with matte blue finish. Tapered 5-1/2" bull barrel with matte blue finish and polished flats. Blowback, single-action trigger. Ambidextrous Ultragrip RX grip. Adjustable, 16-click per revolution Pro-Target sight provides a finer range of adjustment over the industry's standard of 12 clicks per revolution.
