The Ruger Mark IV Competition pistol in .22 LR with a 10-round capacity (brand part no. 40112) is a stainless steel rimfire target pistol built with a slab-sided bull barrel measuring 6.88 inches for maximum accuracy and stability. Ruger finishes the pistol in satin stainless and pairs an internal cylindrical bolt design, which ensures permanent sight-to-barrel alignment, with checkered laminate grips featuring a thumbrest. A simple one-button takedown allows quick field-stripping without tools, and an adjustable rear sight pairs with a drilled-and-tapped receiver for mounting a Weaver- or Picatinny-style optic rail. An ambidextrous manual safety and a push-button magazine release round out the controls, and the pistol ships with two 10-round magazines. Among stainless rimfire semi-auto handguns, this Mark IV Competition configuration favors competitive and precision rimfire shooters.
