Ruger Mark IV 22/45 | .22 LR | 4.4″ TB | 10rd | 40190

The Ruger Mark IV 22/45 is a rimfire target-style pistol built around a precision-molded polymer grip frame and a cold hammer-forged, 4.4-inch threaded bull barrel finished in blued steel. It ships with a factory Picatinny rail, a thread protector for 1/2-28 muzzle accessories, and two 10-round magazines for straightforward range use. For a reliable optic that pairs well with this platform and stays under $1,000, consider a compact red-dot such as the Vortex Venom 3 MOA to preserve the pistol’s sighting line and quick target acquisition. Typical applications for this pistol include range practice and marksmanship training.
