About This Firearm
At 22.3 oz unloaded, the Walther PDP Full Size is the lightest full-size 9mm on the market. It weighs less than the Glock G17 Gen5 at 24.87 oz and the HK VP9 at 25.56 oz while carrying 18 rounds to their 17. The 4.5-inch barrel and 8.0-inch overall length match standard full-size dimensions. The difference shows up during extended carry: 6 oz less than a Sig P320 Full Size (28.3 oz) makes a measurable difference after 8+ hours on the belt line.
The Performance Duty Trigger breaks at 5.6 lbs with barely any pre-travel before hitting a clean wall. Reviewers consistently describe the reset as quick and easy to track by feel. The optic-ready slide accepts 14 different red dot footprints without adapter plates, which beats plate-based systems that add height between the optic and the slide. German manufacturing from Walther's Ulm facility carries a different quality expectation than Turkish or Croatian production. The interchangeable backstraps let you adjust grip circumference to fit your hand.
Walther introduced the PDP in 2021 to replace the PPQ. Early production runs had reports of slide stop lever cracks developing, particularly after high round counts. Walther addressed the part through warranty service and now restricts replacement to factory installation. The PPQ already had a strong following in competitive and duty circles, and the PDP builds on that foundation with the optic-ready slide and improved trigger.

Strengths & Limitations
- At 22.3 oz unloaded, it is the lightest full-size 9mm available. That 6 oz weight savings over a Sig P320 Full Size (28.3 oz) becomes noticeable during all-day carry
- The optic-ready slide accepts 14 different red dot footprints directly without adapter plates, more mounting options than any competitor in the full-size class
- Eighteen-round capacity beats the Glock G17 Gen5 and HK VP9 by one round while weighing less than both
- The 22.3 oz weight means less mass to absorb recoil. Reviewers note the PDP shoots snappier than heavier alternatives like the Sig P320 or HK VP9 during rapid fire
- Walther magazines are less widely stocked than Glock or Sig magazines. Local gun store availability is inconsistent, so ordering online is the reliable option

Frequently Asked Questions
Did Walther fix the early PDP slide stop lever issue?
Early production runs had reports of slide stop lever cracks developing, particularly after high round counts. Walther handles the issue through warranty service rather than direct parts sales, and the component must now be installed at the factory rather than purchased over the counter. If buying used, check the round count and history with the previous owner and contact Walther if any slide stop lever wear is visible.
What is the difference between the PDP Full Size and the PPQ?
The PDP replaced the PPQ in 2021. The PDP adds an optic-ready slide, improved trigger with less pre-travel, and 18-round capacity (versus 15 in the PPQ M2). The grip texture pattern is also different. PPQ holsters do not fit the PDP due to the optic cut changing the slide profile. The PDP is the current production model; the PPQ is discontinued.
What red dots mount directly on the PDP without adapter plates?
The PDP's optic cut accepts 14 footprints including Trijicon RMR, Holosun 407C/507C, Leupold DeltaPoint Pro, Aimpoint ACRO, and Sig Romeo1 Pro. Walther includes mounting hardware for multiple patterns. The direct-mount design eliminates the adapter plate height that Glock MOS and similar systems add between the optic and the slide, giving a lower co-witness with iron sights.
