Description
Walther's PPQ already had one of the best factory triggers in the striker-fired world. The PDP took that foundation and made it better. The Performance Duty Trigger has a shorter pre-travel, a more defined wall before the break, and a quicker reset than the PPQ that preceded it. For a stock trigger, it genuinely competes with guns that cost significantly more, and a lot of people who have shot both will tell you it's the best trigger they've pulled on a striker-fired pistol right out of the box.
What Makes the Walther PDP 5" Full Size Worth a Hard Look
The 5-inch barrel brings a few real advantages: more velocity, a longer sight radius for better iron sight accuracy, and a front-heavy balance that many people find reduces muzzle flip and makes fast follow-up shots easier. The slide is milled low so that a micro red dot sits as close to the bore axis as possible, which is exactly what you want for fast, natural target acquisition. Walther calls it Red Dot Ergonomics, and the grip angle is intentionally tuned to help bring the dot up to your eye naturally. The SuperTerrain serrations on the slide are raised rather than cut in, so they bite into your fingers rather than away from them, which makes racking the slide under stress or with wet hands noticeably more positive than a lot of the competition.
Walther PDP Full Size Optics Setup
The slide comes with a polymer cover plate over the optic cut, and Walther will send you a mounting plate for your chosen red dot free of charge through their website. The rear iron sight dovetail is left intact by the optic cut, and the rear sight is adjustable for both windage and elevation. Glock-pattern aftermarket sights also fit the PDP, so you have good options if you want to upgrade. The Picatinny rail up front means any standard pistol light drops right on.
The frame is polymer with Walther's Performance Duty texture, which is grippy without being rough enough to tear up your hands or snag on clothing. Three internal automatic safeties are built in, plus a loaded chamber indicator so you always know the gun's status at a glance. At 26.9 ounces unloaded, it has enough weight to absorb recoil comfortably without being a burden to carry. Two 18-round magazines are included, and the gun is also compatible with PPQ M2 magazines if you already have those on hand.

Frequently Asked Questions
Does the Walther PDP Full Size come ready to mount a red dot optic?
The slide is factory-milled for a red dot, but it ships with a polymer cover plate over the cut rather than an optic-specific mounting plate. Walther will send you the correct adapter plate for your chosen optic free of charge through their website. Just know that the plate typically ships separately, so if you want to run a red dot day one, order the plate ahead of time.
What optic footprints are compatible with the PDP Full Size slide cut?
The PDP uses a proprietary Walther optic cut that accepts a range of adapter plates offered by Walther directly. Plates are available for popular footprints including Trijicon RMR, Leupold DeltaPoint, and others. The mounting pattern is also similar to Glock MOS, which means a wide range of aftermarket plates and optics will work with it.
Can the Walther PDP Full Size 5" use PPQ magazines?
Yes, the PDP Full Size is compatible with Walther PPQ M2 magazines. This is a nice bonus if you already have PPQ mags in your collection. The PDP ships with two 18-round magazines, which is already a generous package right out of the box.
Is the 5-inch barrel version better for competition or is it mainly a duty pistol?
The 5-inch PDP Full Size works well in both roles. The longer barrel gives you more velocity and a longer sight radius, which helps at distance and makes the gun easier to shoot accurately at speed. It has seen use in USPSA and IDPA competition and holds its own against more expensive dedicated competition guns, largely thanks to the Performance Duty Trigger.
What is the trigger pull weight on the Walther PDP Full Size?
Walther rates the Performance Duty Trigger at approximately 5 pounds, and most real-world testers find it measures close to that. The trigger is widely considered one of the best factory striker-fired triggers available, with a short, clean break and a fast, positive reset that makes follow-up shots easy to manage.
Does the Walther PDP Full Size have any manual safeties?
There is no external manual safety on the PDP. Instead, it relies on three internal automatic safeties, including a trigger safety, drop safety, and firing pin safety. It also features a loaded chamber indicator so you can visually or physically check the gun's status without racking the slide.
