Ruger 40103: Ruger\'s Mark IV Target 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 Weaver- or Picatinny-style rail (rail not included). 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. This model has a stainless steel metal finish.
