Parker Mountain Machine Steel Frame Walther PDP
This guide details the process of building a custom Walther PDP steel frame pistol by combining a steel frame with a modified top end featuring a Parker Mountain Machine (PMM) threaded barrel and dual-port compensator. The video emphasizes that Walther does not sell slides individually, making this a custom build requiring sourced components. The resulting firearm offers a softer shooting experience and fits standard 5-inch steel frame holsters.
