Browning Buck Mark rimfire pistols lead the industry in quality, reliability, accuracy and variety. The Buck Mark Plus UDX stands apart from the rest of the Buck Mark pistol line due to its premium look and feel. The grip frame is machined with finger grooves that match up to the textured wood laminated grips. The slab-side barrel has highly polished flats for a highly attractive accent. The TRUGLO/Marble Arms front fiber-optic sight gives superior target acquisition even in low light conditions, and you can dial it in tight with the Pro-Target adjustable rear sight.
