Description
The PDP name stands for Performance Duty Pistol, and Walther built the full-size 5-inch model to back that up. The 5-inch barrel stretches the sight radius to 7.4 inches, which is the longest in the PDP family, and delivers 9mm velocity near the top of what the cartridge is capable of. That extra barrel length also contributes to a flatter, more forgiving shooting experience on strings of fire. Combine that with a weight of 23.8 ounces unloaded and you've got a full-size pistol that doesn't punish you for a long range session.
The Performance Duty Trigger is genuinely one of the best striker-fired triggers available on a factory production pistol. It breaks clean with a short, tactile reset and sits right around 5.6 pounds, which is a great balance for a pistol that works equally well at the range, on duty, or in a home defense role. Walther also built a stepped chamber into the barrel, a design feature that tightens the tolerances near the chamber throat, contributing to both accuracy and slightly elevated velocities compared to conventional barrel designs.
The optics-ready setup here is more thoughtfully executed than most. Walther mills the slide to seat micro red dots as low as possible, and the optic plate system supports a wide variety of popular footprints including Trijicon RMR, Holosun 507C, Aimpoint ACRO, and Leupold DeltaPoint Pro. Contact Walther directly after purchase and they'll send you the adapter plate for your specific optic at no extra charge. The iron sights are a three-dot setup with an adjustable rear, so the pistol is fully functional without an optic while you decide on a red dot.
The polymer frame is shaped around what Walther calls Red Dot Ergonomics, with a grip angle and grip texture designed to bring an optic-mounted pistol on target naturally. The Performance Duty Texture on the grip panels gives you a secure hold without being abrasive, and the SuperTerrain slide serrations protrude from the slide surface rather than being cut into it, making press checks and malfunction clearances confident even with gloves on. An integrated Picatinny rail and ambidextrous controls round out a platform that's ready to go to work without a trip to the aftermarket first.
This model ships with two 10-round magazines and includes the adjustable rear sight tool. It comes packaged in Walther's standard lockable hard case.

Frequently Asked Questions
What optics are compatible with the Walther PDP Full-Size optic-ready slide?
The PDP's optic-ready slide uses a plate-based adapter system that supports a wide range of popular red dot footprints, including the Trijicon RMR, Holosun 507C, Aimpoint ACRO, and Leupold DeltaPoint Pro. The gun ships with a cover plate installed, but Walther will send you the correct adapter plate for your specific optic free of charge if you contact them after purchase. Additional plates are also available directly from Walther if you want to run multiple optics over the life of the gun.
What makes the PDP trigger stand out compared to other striker-fired pistols?
The Performance Duty Trigger on the PDP is widely regarded as one of the best factory striker triggers available, delivering a clean break and a short, tactile reset at around 5.6 pounds. Most comparable striker-fired pistols ship with triggers that require aftermarket work to reach this level of feel and consistency. It's one of the primary reasons this pistol gets recommended so often for both duty and range use.
Why choose the 5-inch barrel version over the 4" or 4.5" models?
The 5-inch barrel gives you the longest sight radius in the PDP lineup at 7.4 inches, which makes target acquisition a bit more forgiving and supports better accuracy at distance. The longer barrel also squeezes more velocity out of 9mm loads due to a combination of barrel length and Walther's stepped chamber design. If you're prioritizing range performance, duty use, or competition, the 5-inch is the natural choice in the PDP family.
Is the Walther PDP Full-Size comfortable to shoot for extended range sessions?
Most people find the PDP ergonomics to be among the best available in a polymer-framed pistol. The Performance Duty Texture on the grip gives you a secure hold without the aggressive bite of heavily stippled aftermarket grips, and the grip geometry puts your hand high on the bore axis for better recoil management. The pistol also ships with three interchangeable backstraps so you can dial in the fit to your hand size.
Does the Walther PDP Full-Size support +P ammunition?
Yes, the PDP is rated for +P ammunition per Walther's specifications. The stainless steel barrel features a stepped chamber design that handles higher-pressure loads well while also contributing to improved accuracy and velocity with standard pressure rounds. As with any pistol, it's a good idea to confirm your specific load works reliably through your gun before relying on it for any serious purpose.
How many magazines come with the Walther PDP Full-Size 5" and what is the capacity?
This model (UPC 723364220296) includes two 10-round magazines. The PDP full-size platform is also available in a higher-capacity variant that ships with 18-round magazines, so it's worth confirming which version you're purchasing if capacity is a priority. Both variants use the same frame and are compatible with the full range of PDP full-size magazines.
