Ruger's Mark IV features a simple, one-button takedown for quick and easy field-stripping and proper chamber to muzzle cleaning.

The accurate sighting system features a drilled and tapped receiver for Weaver- or Picatinny-style rail. The Mark IV also has an ambidextrous manual safety, push-button magazine release located on the left side, and an ergonomic bolt stop. Included is a washer and two magazines. This Tactical model features a 4.4 threaded barrel, one-piece, precision CNC-machined aluminum grip frame, black oxide metal finish, smooth contoured black synthetic grip, fixed front sight with an adjustable rear, top and bottom Picatinny rails.
