The Mark IV 22/45 Lite series is the latest .22 pistol line from Ruger. The pistol features a lightweight aluminum frame with weight-saving cuts and utilizes the popular 1911-style grip and ambidextrous safety controls to maximize comfort and ergonomics for the user. These pistols also come standard with a threaded barrel for mounting aftermarket and muzzle devices.

Ruger has expanded the Ruger Mark IV 22/45 Lite family of rimfire pistols with a new model that features a mounting position for a standard Shield RMS footprint reflex optic in place of the Picatinny rail. This allows the optic to be mounted lower on the receiver and reduces parallax. It also features a raised front fiber optic sight and an adjustable rear sight that co-witness with most micro red dot optics. The new model has an attractive ventilated rib on top of a clear anodized receiver.

This model features a silver finish and includes two 10-round magazines.
