Upgrade your P320 Full Size for maximum accuracy with the X5 Grip Module. Featuring a deeper trigger guard undercut, a higher back strap and an extended beavertail to ensure a higher grip for better recoil management. It comes standard with a removable grip weight for improved balance, as well as a removable magazine funnel for faster reloading. Works with any Full-Size 9/357/40 Slide. PLEASE NOTE: XSeries grip modules are only compatible with the newer P320 magazines with the circular SIG logo. Gen 1 mags marked Sig Sauer require modification to fit. With the magwell installed, only new style 21rd mags will fit without modification.
