Coastal Blue dyed Sig Sauer P320 X Series grip module assembly comes in medium grip size and works with any full size slide in 9/40/357. Easily install your Sig P320 FCU or 80% Sig Build into this Grip Module Assembly to convert to a P320 X-Series Full Size. Coming from the Factory in White, we put it through our in-house dye process to ensure full coverage using Coastal Blue dye. Dyeing the grip mod stains the actual plastic, meaning it stays as durable and resistant as the polymer used from Sig. As long as the plastic isn't chipped or scratched, the dye will be good. Other colors also available separately.
