The Ruger Mark IV 22/45 is an uniquely crafted and easy to use pistol. The Mark IV 22/45 took new ground with a grip having more of a 1911 style grip as aposed to its siblings with the more classic Ruger style grip you see on the Mark IV's. This pistol's simplicity is its beauty, with a simple one-button takedown for easier acces to field strip and cleaning. This pistol is already drilled and tapped for Weaver or Picatinny style rails for optic mounts. The ambidextrous manual safey can be converted to left side only with the included washer. Directly below the left side safety is the push button magazine release, which has the magazine free drop on release for quick and convenient reloads. 

Note: This firearm is Rimfire.
