The Walther WMP Optic Ready SD in .22 WMR brings the German-made quality of Walther Arms and the WMP series' performance-minded design to shooters who want a lightweight, accurate semi-auto pistol for field work and range days, featuring a 4.9" threaded barrel for suppressor or muzzle device use and an optic-ready aluminum slide that accepts red dots while maintaining serrated surfaces for quick manipulations. With a textured polymer frame for a secure purchase, a 15+1 capacity, a 4.5 lb trigger pull and a 27.8 oz empty weight, this SD model balances controllability and shootability with the ballistics of .22 Magnum for small-game hunting, varmint control and economical target shooting. Fiber optic front and black serrated rear sights give fast target acquisition when an optic isn't mounted, and the three-auto safeties provide multiple layers of handling security expected from modern defensive pistols. Optic-ready versatility, threaded-barrel capability, and rugged Walther construction make this handgun a strong choice for shooters seeking a compact, accurate .22 WMR platform that transitions smoothly from the range to field applications; an FFL transfer is required.
