Ruger Mark IV 22/45 .22LR Pistol 4.4" Threaded Barrel 10rd

The Ruger Mark IV 22/45 delivers precision .22LR performance with modern convenience features that eliminate the frustrations of traditional rimfire pistols. This 4.4-inch threaded barrel model combines match-grade accuracy with suppressor-ready capability for versatile shooting applications.

What Makes This Different

Ruger's one-button takedown system revolutionizes field stripping, requiring no tools and taking seconds instead of the complex disassembly process found in older .22 pistols. The polymer grip frame reduces weight while maintaining the familiar 1911-style grip angle that most shooters prefer. Internal bolt hold-open and magazine disconnect safety provide enhanced functionality over previous Mark series pistols.

Key Features

• One-button takedown system for tool-free disassembly in seconds
• 4.40-inch cold hammer-forged barrel with 1/2x28 threading
• Polymer grip frame with 1911-style grip angle and checkered panels
• Adjustable rear sight and fixed front sight for precision shooting
• Internal bolt hold-open automatically locks bolt after last round
• Magazine disconnect safety prevents firing without magazine inserted
• Picatinny rail machined into receiver for optics mounting

Accuracy remains exceptional with the cold hammer-forged barrel delivering consistent sub-2-inch groups at 25 yards with quality ammunition. The threaded muzzle accepts suppressors and compensators with standard 1/2x28 threading. Competition shooters appreciate the crisp trigger and reliable feeding, while the suppressor-ready design makes this ideal for training and pest control applications.
