The SIG Sauer P320-X full-size grip module (brand part number GRIP-MODX-F-943-M-BLK) is a medium-frame, black polymer grip built for the modular P320-X pistol system. Made by Sig Sauer, this module is rated for 9mm, .40 S&W, and .357 SIG P320 fire control unit conversions, letting you change caliber or frame size without buying a whole new pistol. As a full-size module, it gives you a longer grip and higher magazine capacity than the compact or subcompact options. It is a straightforward way to reconfigure a modular P320 for a different role, from duty carry to a home-defense setup.
