Ruger 40104: Ruger's Mark IV Standard features 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. The one-piece, precision CNC-machined grip frame has a smoothly contoured, grip with natural pointing grip angle with replaceable, checkered grip panels for a non-slip hold. Its internal Cylinderindrical bolt construction ensures permanent sight to barrel alignment and higher accuracy potential than conventional moving slide designs. The contoured ejection port and easy-to-grasp bolt ears allow for durable and reliable operation. Its sighting system features fixed sights and is drilled and tapped receiver for Weaver or Picatinny-style rail for easy mounting of optics. The Mark IV Standard also features a push-button magazine release on the left side of the frame, ambidextrous manual safety, and two 10-round magazines. This model has a 4.75" barrel.
