Ruger Mark IV 22/45 Lite | .22 LR | 4.4in | 43959

The Ruger Mark IV 22/45 Lite is a lightweight .22 LR semi-automatic pistol that pairs a tensioned stainless steel, cold hammer-forged 4.4-inch barrel with a ventilated aerospace-grade aluminum receiver and oversized G10 grip panels for improved handling. It features a simple one-button takedown for fast field-stripping, an adjustable rear sight, and a factory Picatinny rail for optics. This configuration suits precision rimfire target work and general-range training. A compact red-dot such as a Shield RMSc footprint optic (well under $1,000) is a suitable choice for this pistol.
