Ruger Mark IV 22/45 Lite .22 LR 4.4" Threaded Barrel 10+1

The Ruger Mark IV 22/45 Lite delivers exceptional accuracy and versatility in a lightweight platform designed for precision shooting and suppressor use. This .22 LR pistol combines the ergonomics of a 1911-style grip with Ruger's proven Mark IV reliability. The threaded barrel and integrated Picatinny rail expand tactical options while maintaining the classic Mark series reputation for match-grade performance.

What Makes This Different

The Mark IV 22/45 Lite features a unique polymer frame that reduces overall weight by 25% compared to all-steel variants while maintaining structural integrity. The 4.40-inch stainless steel barrel comes factory-threaded at 1/2x28 TPI for direct suppressor mounting. Unlike standard rimfire pistols, this model includes a factory-installed Picatinny rail section for optics mounting without gunsmithing modifications.
