Walther PDP Pro SD Full Size 5.1" IWB (Inside Waistband) Holster
This IWB Inside Waistband Holster is precision-designed for the Walther PDP Pro SD Full Size 5.1", offering secure concealed carry, adjustable retention, and a streamlined profile for everyday use. The open muzzle design supports the Pro SD configuration while maintaining reliable concealment.
Optics-Ready & Suppressor-Height Friendly Design
The holster profile is cut to allow red dot sights to be mounted on the pistol, supporting modern optics-equipped carry setups. An open muzzle allows compatibility with threaded barrels and compatible compensators, provided the compensator does not extend past the sides of the slide or exceed the slide height.
Precision-Molded Fit & Adjustable Retention
Each holster is vacuum-formed using a precision-machined mold created from a CAD model of the actual Walther PDP Pro SD firearm. Every holster is formed, trimmed, and folded in-house, then test-fit with the real pistol to ensure proper retention and consistent draw performance.
Retention is easily adjustable, allowing the fit to be set to your personal preference.
