The Mark IV 22/45 Lite series is the latest .22 pistol line from Ruger and this RMS-footprint model swaps the Picatinny rail for a lower mounting position optimized for Shield RMS-style reflex optics. That lower optic position reduces parallax and offers a cleaner sight picture for fast target acquisition. Shop this product

Design & Ergonomics

The pistol uses a lightweight aluminum frame with strategic weight-saving cuts and a ventilated rib atop a clear anodized receiver, delivering a balanced feel without excess mass. The 1911-style grip and ambidextrous safety controls maximize comfort and make the transition simple for shooters familiar with full-size defensive pistols. The model ships in an attractive silver finish and includes two 10-round magazines, keeping spare magazines on-hand for range sessions.

Controls and Sights

This version includes a raised front fiber optic sight and an adjustable rear sight that co-witnesses with most micro red dot optics — a practical setup for both iron-sight drills and optic-led shooting. The threaded barrel allows attachment of muzzle devices or suppressors where legal, expanding its utility for specialized training or noise reduction.

Performance and Use Cases

Chambered in .22 LR, the Mark IV 22/45 Lite delivers minimal recoil and inexpensive ammunition costs, ideal for high-volume practice, fundamentals training, and casual plinking. Ruger’s reputation for reliable rimfire actions makes this model notable for consistent function and user-friendly takedown via the Mark IV’s simplified disassembly system.
