Walther WMP SD | .22 WMR | 4.9in Threaded | 5220301

The Walther WMP SD is a semi-automatic pistol chambered in .22 Winchester Magnum (.22 WMR) built on a polymer frame with an optics-ready aluminum slide and a 4.9-inch threaded barrel. It ships with two 15-round magazines and three optic adapter plates for Walther’s proprietary slide cut. This configuration suits precision rimfire shooting and extended-range small-game varmint work where lightweight, low-recoil handling and an optics-ready slide are desirable. A compact red-dot such as the Holosun 507C (priced well under $1,000) pairs well with the WMP SD and fits via the included adapter plates; optics are sold separately.
