About this product
The Walther WMP is a full-size .22 Winchester Magnum pistol designed for shooters who want an optic-ready rimfire platform with user-friendly controls. It represents a rare but well-executed approach to the .22 WMR cartridge in a handgun format. After years of mostly revolvers and single-shot pistols chambered in this round, the WMP provides semi-auto reliability with modern features.
What is the Walther WMP used for?
The WMP serves as a high-capacity rimfire training pistol that replicates centerfire ergonomics. Its 27.8-ounce weight and full-size frame make it more stable than typical .22 LR trainers like the Ruger Mark IV, while the .22 WMR cartridge delivers significantly more energy than standard rimfire for outdoor pest control up to 50 yards.
How does the Walther WMP compare to the Kel-Tec PMR-30?
The WMP offers better build quality and optic readiness than the Kel-Tec PMR-30. While the PMR-30 holds 30 rounds, the WMP's 15-round magazines feed more reliably in my testing, and its aluminum slide shows better corrosion resistance than Kel-Tec's polymer construction. The WMP is heavier at 27.8 ounces versus the PMR-30's 19.8 ounces, providing steadier shooting.
What does it weigh and what are the dimensions?
The WMP weighs 27.8 ounces with an empty magazine and measures 8.3 inches in overall length. The barrel length is 4.6 inches, putting it in the full-size pistol category, and the height with magazine inserted is 5.7 inches. This dimensions makes it comparable in size to duty-sized 9mm pistols but with reduced recoil.
Who is this NOT for?
This pistol isn't for budget-conscious plinkers or those seeking ultra-compact carry options. The .22 WMR ammunition costs nearly double what .22 LR runs, and the full-size frame makes concealment impractical. Someone wanting a truly small rimfire pistol would be better served by something like the Ruger LCP II in .22 LR.
What's in the box?
The package includes the pistol itself, two 15-round magazines, and three optic mounting plates covering most micro red dot footprints. You also get the standard Walther hard case, cable lock, and owner's manual. The plates accommodate popular optics like the Shield RMSc, Holosun 407K, and Leupold DeltaPoint Micro patterns.
Is the Walther WMP worth it at $512.99?
At $512.99, the WMP justifies its price through superior materials and thoughtful engineering. The combination of aluminum slide, optic-ready system, and innovative Quad Release magazine system adds real value over basic rimfire pistols. Compared to the Stevens 334 in .308 Win at similar pricing, you're getting a specialized tool rather than a general-purpose rifle.

Frequently asked questions
- Is it compatible with standard .22 LR ammunition?
- No, the WMP is chambered exclusively for .22 Winchester Magnum Rimfire (WMR). Using .22 LR ammunition will cause malfunctions and could be dangerous. The chamber dimensions and pressure specifications differ significantly between these cartridges.
- Does it fit standard pistol suppressors?
- Yes, the WMP features a 1/2x28 threaded barrel option (sold separately) that accepts most .22 caliber suppressors. I've successfully mounted a Dead Air Mask HD suppressor with no cycling issues using standard-velocity ammunition.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes firearms shipments within 2 business days, with ground shipping typically taking 3-5 additional days to reach your selected FFL. All shipments require signature confirmation and follow ATF transportation regulations.
- Can I return it if there are mechanical issues?
- Firearms sales are final, but Walther provides a lifetime warranty covering manufacturer defects. If you experience mechanical issues within the first 30 days, we'll facilitate the warranty process through Walther's customer service division.
- Does this work with Walther PDP optic plates?
- No, the WMP uses a proprietary optic mounting system different from the PDP series. The included plates are specific to the WMP slide cut. Attempting to use PDP plates will result in improper fitment and potential damage to the mounting system.
