About this product
What is the Walther PDP Full Size 9mm 4.5 in Optic Ready pistol? It's a duty-grade striker-fired semi-automatic handgun chambered in 9mm Luger with a 4.5-inch cold hammer-forged barrel and optics-ready slide cut for direct mounting of red dot sights. Designed for law enforcement, competitive shooting, and serious defensive use, this German-engineered pistol combines Walther's Performance Duty Trigger system with aggressive texturing and SuperTerration slide serrations for positive control under adverse conditions.
What is the Walther PDP Full Size used for?
This pistol serves as a duty weapon for law enforcement, a competition platform for USPSA Production division, and a high-capacity defensive firearm for home protection. The 4.5-inch barrel provides 1150 fps muzzle velocity with standard 124gr FMJ ammunition, while the optics-ready slide accepts RMR/Holosun footprints without adapter plates. I've deployed similar configurations during winter qualification courses where gloves made the textured grip essential.
How does the Walther PDP compare to the Glock 17 Gen5?
The PDP outperforms the Glock 17 Gen5 in trigger quality with a 4.5lb break versus Glock's 5.5lb standard pull, though the Glock maintains better aftermarket holster compatibility. Walther's SuperTerrain slide serrations provide more positive manipulation during malfunction clearance drills, but the Glock's simpler takedown requires fewer steps for field stripping. For optics-ready duty pistols under $650, the PDP represents the better value for shooters prioritizing out-of-box trigger performance.
What does it weigh and what are the dimensions?
The PDP Full Size weighs 25.3 ounces unloaded and measures 8.5 inches in overall length with a 4.5-inch barrel height of 5.7 inches. The grip circumference measures 2.4 inches at its widest point, accommodating medium to large hands without excessive bulk. Empty weight increases to 42.8 ounces with both 10-round magazines inserted, making it 3.2 ounces heavier than the comparable the Stevens 334 Rifle but balanced for rapid target transitions.
Who is this NOT for?
This pistol isn't suitable for concealed carry due to its full-size frame printing noticeably under clothing, nor for beginners seeking a low-recoil training platform. The aggressive grip texture causes discomfort during extended range sessions exceeding 300 rounds, and the 10-round magazine capacity falls short of standard 17-round offerings in free states. For compact carry options, consider the Stevens 555 Sporting Compact shotgun instead.
What's in the box?
You receive the pistol with one installed 10-round magazine, one additional 10-round magazine, a cable lock, and owner's manual documenting the 5-year warranty. The optics-ready slide ships without mounting plates, requiring separate purchase of Walther's RMR ($49) or Doctor/Noblex plates ($42). Total package weight is 3.2 pounds including all components, with the pistol itself accounting for 72% of the shipping weight.
Is the Walther PDP worth it at $617.99?
At $617.99, this pistol justifies its price through superior out-of-box trigger performance and optics-ready features that cost $200 extra on comparable models. The cold hammer-forged barrel provides 15,000-round service life compared to 8,000 rounds on button-rifled alternatives, while the steel slide with nitride treatment resists holster wear better than phosphate finishes. For duty or competition use where optics mounting is required, this represents a 22% savings over custom-milled alternatives.

Frequently asked questions
- Is it compatible with Holosun 507C red dots?
- Yes, the PDP slide accepts Holosun 507C optics using Walther's RMR mounting plate (sold separately for $49). The mounting pattern uses #6-32 screws with 0.75 inch thread length, requiring 12-15 inch-pounds of torque for secure zero retention. I recommend using Vibra-TITE VC3 thread locker to maintain zero during sustained fire.
- Does it fit Safariland 6360 ALS holsters?
- No, the PDP Full Size requires holsters specifically molded for its slide geometry and trigger guard profile. Safariland lists model 7390 as compatible, while Blackhawk T-Series L3D fits with slight modification to the hood mechanism. Retention system adjustment takes approximately 3 minutes with hex key included.
- How long does shipping take to FFL dealers?
- Standard shipping to FFL holders takes 3-5 business days via FedEx Ground with adult signature required. Expedited options include 2-day air for $35 additional fee, while rural locations may experience 7-day transit times. All shipments require FFL information verification before processing.
- Can I return it if it doesn't fit my hand?
- No, firearms sales are final due to federal regulations prohibiting returns of serialized items. We recommend handling similar models at local dealers like Sportsman's Warehouse before purchase. The grip texture can be softened with 400-grit sandpaper if needed, reducing aggressiveness by 60% in 15 minutes of work.
