This Service is Offered on your provided Walther PDP slide and barrel.

We CNC machine a rectangular window with a beautiful chamfer at the 12 O’clock Position and Laser Port 5 Circular Ports centered in the window cut.

In addition to the window cut and ports we offer an extensive library of refinishing options for Cerakote and DLC Coating.

We Do Not Offer Cerakote for barrels to due being such a high wear part.

Refinishing is not required but highly recommended. PWI is not responsible for rusting due to neglected metal treatment.

If your Cerakote color Preference is not listed please contact us for other color option.

We also Offer DLC Coating for both Slides and barrels if you’d prefer the exceptional wear resistance of DLC on either your slide, barrel or both Click Here to see the colors we offer!

If DLC is desired please add this service to your cart, select no cerakote, and add our DLC Coating as well. (Please Note DLC Adds an additional 3 weeks to lead time)
