The WCP320 takes the SIG P320 chassis and runs it through the Wilson Combat custom shop — new grip module, trigger job, barrel, and slide cuts that transform a solid duty pistol into a genuinely refined shooter. It brings Wilson-level fit and finish to a platform already trusted by the U.S. military. Shooters who prefer a striker trigger but want Wilson quality finally have an option.
