Overview
The Ruger MKIV 22/45 pistol, chambered in .22LR, is engineered for reliability and user convenience, establishing its utility for target acquisition, recreational shooting, and fundamental training exercises. This model incorporates a 5.5-inch precision-machined barrel, optimizing projectile stability and contributing to consistent shot placement.
Key Features
Precision Engineering & Ergonomics
- Precision Barrel: The 5.5-inch cold hammer-forged barrel is designed to maintain consistent bore dimensions, directly supporting projectile stability and accuracy for consistent shot placement.
- Familiar Grip Angle: The 22/45 grip frame geometry mirrors that of the M1911 pistol, providing an anatomically congruent interface for shooters accustomed to full-size handgun platforms. This design facilitates skill transfer and reinforces proper grip mechanics during training.
Streamlined Maintenance Protocol
- Simplified Takedown: A significant design advancement in the MKIV series is the single-button takedown mechanism. This permits rapid, tool-free field stripping, substantially mitigating the complexity and time required for routine cleaning and maintenance procedures. This feature directly enhances the firearm’s operational readiness.
Robust Construction & Safety Integration
- Durable Construction: Constructed with a lightweight, high-strength polymer frame and a blued alloy steel barrel, the MKIV 22/45 offers a durable yet balanced operational weight without compromise to structural integrity.
- Adjustable Sights: The sight system comprises a fixed front sight paired with an adjustable rear sight, facilitating precise elevation and windage zeroing to optimize target engagement.
- Ambidextrous Safety: An integrated ambidextrous manual safety selector ensures secure handling for both right and left-handed operators, enhancing operational versatility and compliance with safety protocols.
