Walther PDP Compact Pro SD 9mm 15+1 4.6" Threaded Barrel FDE

The Walther PDP Compact Pro SD delivers suppressor-ready performance in a carry-optimized package. This 9mm pistol combines the proven PDP platform with professional-grade features including a factory-threaded barrel and optics-ready slide configuration.

What Makes This Different

The Pro SD variant stands apart from standard PDP models with its factory-threaded 4.6-inch barrel, eliminating the need for aftermarket modifications. The optics-ready slide accepts popular red dot sights without additional machining, while the serrated slide surface provides enhanced grip in adverse conditions. This configuration bridges the gap between duty pistols and specialized suppressor hosts.

Key Features

• Factory-threaded 4.6" barrel with 1/2x28 threading for suppressors and compensators
• Optics-ready slide cut compatible with popular red dot sight mounting systems
• 15+1 capacity with flush-fit magazine in compact frame size
• FDE polymer frame with integrated Picatinny rail for lights and lasers
• Performance Duty textured grip with ergonomic finger grooves and palm swells
• Flared magwell for faster reloads during competition or duty use
• Serrated slide surfaces for positive manipulation in wet conditions

Field testing demonstrates consistent sub-2-inch groups at 25 yards with quality ammunition. The threaded barrel maintains accuracy when paired with suppressors, making this suitable for tactical applications where sound signature matters. Competition shooters appreciate the flared magwell and textured grip during rapid fire strings, while the compact dimensions allow for concealed carry when needed.
