This Ruger Mark IV 22/45 is a semi-automatic handgun chambered in 22 LR. Perfect for plinking, target shooting, and competition, it is crafted with 1911-style double-diamond checkered polymer grips and a bull barrel. Features include an ambidextrous manual safety and a magazine disconnect that prevents discharge when the magazine is removed. The receiver is drilled and tapped for an accessory rail, and maintenance of the Mark IV 22/45 is a breeze thanks to the simple, one-button takedown.
