Walther PDP Full Size 4.5" IWB (Inside Waistband) Holster
This IWB Inside Waistband Holster is precision-built to fit the Walther PDP Full Size 4.5", offering secure concealed carry with adjustable retention and a slim, comfortable profile. The holster is also compatible with the Walther PDP Full Size 4" and Compact 4" models.
Optics-Ready Design for Everyday Carry
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 design allows use 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 firearm. All holsters are formed, trimmed, and folded in-house, then test-fit with the real pistol to ensure consistent retention and reliable draw performance.
The retention is easily adjustable, allowing the fit to be set to your personal preference.
