Key Features

• Optics-Ready Slide – The BLK OR (Optics Ready) model is pre-milled for micro red dot sights, making it easy for new shooters to acquire targets faster. Why it matters: You can mount a dot without sending the slide to a gunsmith, saving time and money.
• 10-Round Magazine – A standard 10-round capacity gives you plenty of shots before reloading, perfect for practice sessions or small-game hunting. Why it matters: More rounds mean less downtime, so you can focus on building muscle memory.
• .22 WMR Chambering – The .22 Magnum delivers higher velocity than .22 LR, with flatter trajectory and better energy for varmints or steel targets. Why it matters: You get magnum performance without the heavy recoil of centerfire calibers, ideal for youth shooters.
• Ambidextrous Safety – A frame-mounted safety works for left- and right-handed shooters, adding a layer of security for family training. Why it matters: Teaching safe handling is easier when controls fit every family member.
• Lightweight Polymer Frame – At just over 1.5 pounds, the WMP is easy to carry on hikes or hold steady during long range sessions. Why it matters: Less fatigue means more accurate shots, especially for new shooters.

Who It’s For

The Walther WMP is built for families who want a rimfire pistol that can do more than plink. It’s a great choice for introducing teenagers to magnum rimfire shooting, because the .22 WMR gives them a taste of power without punishing recoil. Outdoor enthusiasts will appreciate the lightweight build for backpacking trips where varmint protection is needed. Beginners who want to train with an optics-ready pistol will find the WMP easy to learn on, thanks to its low bore axis and crisp trigger.

Pros and Cons

Pros: Optics-ready out of the box, very low recoil, reliable feeding with .22 WMR, ambidextrous safety for lefties, and a 10-round magazine that’s plenty for range work.

Cons: The trigger pull is a bit heavier than some target pistols, with a 5.5-pound break that may feel stiff for smaller hands. Per Walther specs, the factory trigger is designed for safety, but aftermarket springs can lighten it if needed.
