The Walther PDP F-Series Pro-E is a semi-automatic 9mm pistol with a 3.5-inch barrel and an 18-round capacity. It is optics-ready from the factory.

Walther PDP owners in the F-Series configuration often point to the grip ergonomics as the standout feature. The F-Series frame shape is specifically shaped for a higher grip, and those with smaller hands find it a better fit than full-size striker pistols. The Pro-E designation and 18-round capacity in a compact package get consistent positive attention.

The optics-ready cut is appreciated by those who want to mount a red dot without additional milling. Some owners note the proprietary Walther footprint requires an adapter for popular red dot sights, which adds a small inconvenience.

The PDP F-Series Pro-E sits at a premium price point relative to other compact 9mm pistols. Most owners feel the trigger and fit-and-finish justify the cost, though a portion of buyers find comparable reliability at a lower price elsewhere in the market.
