WP was established in Longmont Colorado in 1970. We are anĀ ISO 9001:2015 certified Contract Manufacturer.

Over the years, WP has evolved and strengthened its customer-oriented focus to include a precision machine shop staffed with skilled tool makers and production machinists, an engineering staff capable of evolving a sketch into a finished part, and skilled molding processors to create the product you would expect from an american manufacturer!

In 2009 a niche market was developed as a result of companies that required substantial molding volume, quality components and on-time delivery for the manufacturing of firearms accessories. Our product line includes, Magazines, Trigger Grips, Butt Stocks, Round Limiters, Carry Handles, Grip Panels, and many others.

We employ state-of-the-art technologies like 5-Axis machining, 3D printing, and Mold Flow Analysis that permit designs to be quickly evaluated in production-like materials before cutting a mold. In addition, we are capable of performing Finite Element Analysis which can be a critical step in the manufacturing process to mitigate risk both technologically and financially.
