Ruger 40118: Ruger\'s Mark IV Hunter Pistol is a simple, one-button takedown for quick and easy field-stripping and proper chamber to muzzle cleaning. A recessed button in the back of the frame allows the upper receiver to tilt up and off of the grip frame without the use of tools. It features an one-piece, precision CNC-machined grip frame, ergonomic bolt stop, a contoured ejection port and easy-to-grasp bolt ears allow for durable and reliable operation round after round. The accurate sighting system features adjustable rear sight and drilled and tapped receiver for easy mounting of optics. Ambidextrous manual safety positively locks the sear in the \"safe\" position when applied. Safety can be converted to left-side only with included washer. This model includes two 10-round magazines.
