Ruger Mark IV 22/45 22 LR 4.4" 10rd Threaded Optic Ready Pistol

The Ruger Mark IV 22/45 pairs the proven Mark IV action with a polymer frame that replicates the 1911 grip angle, so shooters who train on a 1911 can run a rimfire trainer that points the same way. This 40190E configuration adds a 4.4" threaded barrel, an optic ready slide, and comes with two magazines for solid range time out of the box. The adjustable rear sight is a big deal for anyone chasing small targets with a 22 pistol.

The threaded muzzle takes a rimfire suppressor directly — no adapter needed — making this a popular suppressor host for cheap, quiet range time. Mark IV one button takedown drops the upper off for cleaning in seconds, a real upgrade over the old Mark II and III bushings. The checkered polymer grip frame keeps the weight down and the 22/45 designation right in the grip. Two factory 10 round magazines feed cleanly and the single action trigger breaks clean once you learn its character. For training, trigger work, or a suppressor host, the Mark IV 22/45 has earned its reputation.
