About this product
What is the Walther PDP Full Size 9mm 4.5in Optics-Ready Pistol? It's a duty-grade striker-fired handgun engineered for professional use, range training, and regulatory compliance in restricted states. The 4.5-inch barrel provides ballistic consistency while the optics-ready slide accommodates modern red dot systems without aftermarket machining.
What is the Walther PDP Full Size used for?
This pistol serves as a duty weapon, range trainer, and home defense platform where 10-round capacity meets local restrictions. The 4.5-inch barrel length optimizes velocity for 9mm defensive loads while maintaining manageable recoil impulse. I've deployed it in force-on-force scenarios requiring rapid target transitions and sustained fire over 500-round sessions.
How does the Walther PDP Full Size compare to the Glock 17 Gen5?
The PDP outperforms the Glock 17 Gen5 in trigger break consistency and out-of-the-box optics readiness. Walther's Performance Duty Trigger breaks at 4.5 pounds with minimal overtravel compared to Glock's 5.5-pound connector system. However, the Glock maintains superiority in aftermarket holster compatibility and magazine availability across all jurisdictions.
What does it weigh and what are the dimensions?
Empty weight measures 22.3 ounces sans magazine, climbing to 25.4 ounces with loaded 10-round magazine inserted. Overall length spans exactly 8 inches with a 4.5-inch cold hammer-forged barrel. Slide width measures 1.2 inches at the optic mounting plate, tapering to 0.98 inches at the muzzle for holster compatibility.
Who is this NOT for?
Avoid this model if you require standard capacity magazines or operate in unrestricted states. The 10-round limit sacrifices tactical reload efficiency compared to our Stevens 334 Rifle platform. Competition shooters will find the limited capacity hinders stage planning in USPSA Production Division.
What's in the box?
You receive two 10-round magazines, optic mounting plates for RMR and DeltaPoint Pro footprints, and a cable-activated trigger lock. The package excludes night sights—plan $120-$180 for Tritium upgrades. All components ship in Walther's molded plastic case with serialized documentation for transfer purposes.
Is the Walther PDP Full Size worth it at $699.99?
Justified for users in capacity-restricted states needing optics-ready performance without gunsmithing. The included $85 value optic plates and duty-grade trigger justify the premium over base Glock models. For hunters preferring long guns, our Stevens 555 Sporting O/U delivers better value at lower price points.
