Walther PDP Full-Size PRO SD 9mm – 5.1 in Threaded Barrel, Optics-Ready Slide, 18+1 Capacity
The PDP PRO SD takes Walther’s already respected Performance Duty Pistol and adds range-ready upgrades straight from the factory. A 5.1-inch hammer-forged, nitrided barrel ends in a 1/2x28 threaded muzzle, while suppressor-height steel sights and an optics-ready slide make it turnkey for red dots or suppressors. Coupled with Walther’s flat-faced Dynamic Performance Trigger and aggressive SuperTerrain serrations, this full-size 9mm offers an out-of-the-box setup that meets modern duty, competition, or defensive needs with minimal additional work.

This PRO SD variant ships with a 5.1-inch threaded barrel cut from carbon steel, finished in durable nitride, and treated to Walther’s polygonal rifling for easy maintenance and long service life. The 1/2x28 thread pattern is the U.S. standard for 9mm muzzle devices, making suppressor or compensator installation straightforward.
The slide arrives milled for direct-mount red-dot plates and uses raised SuperTerrain serrations at both ends for a firm grasp, even with gloves or under recoil. Suppressor-height three-dot steel sights co-witness with most optics and clear suppressor bodies without additional parts.
Inside the glass-fiber-reinforced polymer frame, Walther’s flat Dynamic Performance Trigger breaks at approximately 5.6 lb with a short, tactile reset for fast follow-up shots. The reversible push-button magazine release and three interchangeable backstraps allow quick adaptation to different hand sizes and shooting preferences.
Factory steel magazines hold 18 rounds each, giving the pistol an 18+1 capacity in its full-size footprint. An accessory rail molded into the dust cover supports weapon lights or lasers, and CIP N and DE proof marks confirm German manufacture and quality control.
