Ruger Mark IV 22/45 Tactical 22 LR 4.4 in 10+1 Blued Slide Threaded Barrel

The Ruger 40149 Mark IV 22/45 Tactical is a 22 LR semi-auto pistol from Ruger's Mark IV series that pairs the classic 1911-style ergonomics with modern tactical features, making it an excellent choice for range training, rimfire plinking, and suppressor-ready small game work; the blued steel slide rides on an alloy steel receiver with Ruger's one-button takedown that lets the upper tilt off for tool-free field-stripping and true chamber-to-muzzle cleaning, while the internal cylindrical bolt design locks permanent sight-to-barrel alignment for better inherent accuracy than moving-slide designs. The 4.40" threaded barrel (1/2"-28) and top and bottom Picatinny rails let you mount optics, lights or run a suppressor, and the adjustable rear sight with fixed front sight gives a clear, contrast sight picture for fast target acquisition. Controls are user-friendly for right- or left-handed shooters with an ambidextrous manual safety that positively locks the sear and a left-side push-button magazine release; the polymer grip frame with black checkered 1911-style panels offers familiar grip angle and control, while features like a magazine disconnect and ergonomic bolt stop add safe, repeatable operation. Weighing 33.3 oz and measuring 8.50" overall, this 10+1 capacity, SAO Ruger Mark IV 22/45 Tactical is built for shooters who want a serviceable, accurate .22 LR platform with threaded-barrel versatility and rugged, range-ready construction.
