Overview: What the WALTHER WMP Brings to the Table
The WALTHER WMP occupies a niche many shooters appreciate: a full-size chassis chambered in .22 WMR that retains the feel and controls of centerfire duty pistols while offering lightweight recoil and economical shooting. With a 15+1 capacity and a 4.50″ stainless steel barrel, this pistol is designed for extended range sessions, precision practice, and training scenarios where you want the handling characteristics of a larger pistol without the cost of centerfire ammunition.
Design & Build
Slide and Barrel
The silver serrated aluminum slide reduces overall weight compared to steel while offering durable serrations for positive manipulation. The 4.50″ stainless steel barrel enhances accuracy potential and resists corrosion—an important trait for a service-style pistol you’ll run through many rounds on the range.
Frame and Controls
The black polymer frame keeps the WALTHER WMP comfortable for long sessions and helps absorb felt recoil. The full-size frame provides a full hand purchase and stabilizes follow-up shots. Controls are positioned for intuitive access; whether you’re transitioning from another Walther or training new shooters, the layout promotes consistent presentation and repeatable trigger control.
Capacity and Feed System
A 15+1 magazine capacity in .22 WMR is notable. That capacity reduces reload frequency during extended drills and allows for realistic defensive or competition-style sequencing when practicing draw-and-engage drills. Feeding .22 WMR reliably requires magazines and springs tuned for the rimmed cartridge; the WALTHER WMP’s design addresses these needs with a factory feed system optimized for consistent lockup and cycle timing.
Performance: The .22 WMR Advantage
.22 WMR offers higher velocity and energy compared to .22 LR while maintaining low recoil and low noise relative to centerfire cartridges. That balance makes it an excellent choice for high-volume training, precision dry- and live-fire drills, and small-game applications where legal and appropriate. The WALTHER WMP’s 4.50″ barrel helps extract the most consistent velocity from .22 WMR loads, improving point-of-impact stability and extending useful accuracy out past typical rimfire distances.
Accessory-Ready: Picatinny Rail and Optics Compatibility
The integrated Picatinny rail on the WALTHER WMP’s polymer frame opens the platform to lights, lasers, and training optics. Paired with the serrated slide that allows for sight purchase during press checks and manipulations, the rail makes this pistol adaptable for a variety of roles. For shooters who want to install a compact red dot or a tactical light for low-light training, the rail provides the necessary mounting surface without aftermarket modification.
Practical Applications
From an instructor’s perspective, the WALTHER WMP is a strong candidate for transitional training programs—where instructors teach fundamentals on a rimfire that simulates the ergonomics and trigger geometry of larger pistols. It’s also suited for recreational target shooting and rimfire-specific competitions. Because the platform mirrors full-size handling, it’s effective for ingraining stance, sight alignment, and trigger control before stepping up to centerfire calibers.

Maintenance and Reliability Considerations
Polymer and aluminum construction reduces weight but requires routine inspection of slide-to-frame fit and lubrication of the stainless barrel to maintain peak performance. The WALTHER WMP’s design supports straightforward field stripping for cleaning. Use high-quality .22 WMR ammunition for best reliability, and rotate magazines and springs periodically if you run high round counts.
Accessories and Customization
The Picatinny rail makes accessory choices simple. Many shooters will add a compact optic for target work or a small light for low-light familiarization drills. Standard Holster fitment will vary due to frame dimensions; test fit any holster intended for daily carry or training before committing to a configuration.
Final Assessment
For shooters seeking a full-size rimfire that feels like a duty pistol while keeping recoil and operating costs low, the WALTHER WMP offers a focused package: full-size frame ergonomics, a 15+1 capacity in .22 WMR, a 4.50″ stainless steel barrel for improved accuracy, and a silver serrated aluminum slide on a black polymer frame with an integrated Picatinny rail. At $399.99, it provides a competitive value for training-oriented platforms and recreational shooters alike.
