Walther WMP .22 WMR Optic Ready Pistol, Black, 2 Mags
About this product
The Walther WMP is a semi-automatic pistol chambered in .22 Winchester Magnum designed for shooters who want an optics-ready platform with ambidextrous controls and modern ergonomics. It features a machined aluminum slide on a polymer frame, weighing 27.8 ounces empty, and ships with two magazines and three optic adapter plates for direct mounting of micro red dots.
What is the Walther WMP used for?
The WMP serves primarily as a low-recoil training and small-game hunting pistol with optics compatibility. Its .22 WMR cartridge generates approximately 35% less recoil impulse than 9mm while maintaining effective terminal ballistics for varmints out to 75 yards. The 4.6-inch barrel and accessory rail support light/laser combinations for low-light pest control applications.
How does the Walther WMP compare to the Kel-Tec PMR-30?
The WMP offers superior optics mounting and ergonomics compared to the Kel-Tec PMR-30's higher capacity. While the PMR-30 holds 30 rounds versus the WMP's 10-round magazines, Walther's aluminum slide and Quad Release system provide more reliable extraction and faster magazine changes. For training fundamentals and suppressor use, the WMP's optics-ready design and 1/2x28 threaded barrel (adapter required) make it the better platform despite lower capacity.
What does it weigh and what are the dimensions?
The pistol weighs 27.8 ounces empty and measures 8.1 inches in length with a 4.6-inch barrel height. The slide width measures 1.1 inches, while the overall height with magazine inserted is 5.9 inches. These dimensions place it squarely between compact and full-size handguns, comparable to our Stevens 334 Rifle in handling balance.
Who is this NOT for?
The WMP isn't suitable for defensive carry or high-volume shooting due to .22 WMR's rimfire ignition limitations. The cartridge costs approximately $0.35 per round versus $0.12 for .22 LR, making sustained fire impractical for budget-conscious shooters. Those needing immediate defensive capability should consider centerfire options like the Stevens 555 Sporting O/U for home defense scenarios.
What's in the box?
The package includes the pistol, two 10-round magazines, three optic adapter plates (RMSc, Doctor, and J-Point footprints), cable lock, and owner's manual. The plates accommodate over 90% of micro red dots on the market without additional gunsmithing. Total unboxing to range-ready time averages 8 minutes with proper optic mounting tools.
Is the Walther WMP worth it at $512.99?
At $512.99, the WMP justifies its price through machining quality and included optics mounting system. Comparable .22 WMR pistols like the Kel-Tec PMR-30 retail for $450 but require $75-150 in aftermarket plates for optic mounting. For shooters wanting immediate optics capability and Walther's machining standards, the WMP delivers value where it matters most.

Frequently asked questions
- Is it compatible with suppressor attachments?
- Yes, with a 1/2x28 threaded barrel adapter available from Walther for $45. The adapter requires professional installation but maintains concentricity for .22 caliber suppressors like the SilencerCo Sparrow. Total weight increase with suppressor averages 4.2 ounces.
- Does it fit standard pistol holsters?
- No, the WMP requires custom holsters due to its 1.1-inch slide width and accessory rail profile. Blackhawk and CrossBreed offer WMP-specific models starting at $65. Holster compatibility matches full-size 1911 patterns rather than compact carry pistols.
- How long does shipping take to FFL dealers?
- Standard shipping averages 3-5 business days to continental US FFL holders after verification. Alaska/Hawaii shipments require 7-10 days via UPS Ground. All shipments include tracking and require dealer notification within 2 hours of processing.
- Can I return it if it has mechanical issues?
- Yes, Ironclad Armory accepts returns within 30 days for mechanical defects verified by our armorers. Warranty claims process typically resolves within 10 business days including shipping. Non-mechanical returns incur a 15% restocking fee per ATF compliance requirements.
- Does this work with Holosun 507C optics?
- No, the included plates support micro dots only. The Holosun 507C requires an RMR adapter plate available from CHPWS for $39. The optic adds 1.3 ounces and may require suppressor-height sights for co-witnessing.
