Precision meets versatility – The Walther PDP SD Series
The Walther PDP FS 5.1" SD was specifically developed for shooters who wish to operate their pistol with a suppressor. The factory-installed threaded barrel in 9mm Para with the internationally standardised 1/2x28 TPI thread enables the quick and secure mounting of commercially available suppressors. The raised Suppressor High Sights ensure a clear line of sight at all times – even when a compact suppressor is attached.
The 5.1-inch barrel provides outstanding muzzle velocity and superior accuracy, excelling in both sporting competition and tactical training. With a magazine capacity of 18 rounds, the PDP FS SD also offers ample reserves for intensive training sessions.
Walther Performance Duty Trigger – The difference in the details
The heart of every Walther PDP is the Performance Duty Trigger (PDT). This patented trigger offers a short, clean break with a defined reset – ideal for rapid follow-up shots and precise single fire. Combined with the ergonomically optimised grip and aggressive texturing, the pistol sits securely and controllably in the hand – even under stress or in wet conditions.
Optics-Ready for modern targeting optics
The milled slide of the Walther PDP FS 5.1" SD is Optics-Ready and supports the direct mounting of a wide range of compact red dot sights without additional adapter plates. This allows the pistol to be quickly and easily equipped with modern targeting optics – for even faster target acquisition and improved accuracy.
