From the beginning, the P320 was built to be a pistol that could adapt to meet the user's specific needs. From grip modules and magazines to custom slides, barrels, and optics, the P320 can be configured in thousands of different ways to make your P320 unique and exactly the pistol you are looking for. The P320 CustomWorks Studio FCU program takes that idea and brings it to an unprecedented new level. Take a look at the video to get a more in-depth overview of what this program has to offer.
