Sig Sauer P320 X-Five Grip Module Full-Size Medium Black

The Sig Sauer P320 X-Five Grip Module is a full-size, medium grip module in black polymer designed to convert or upgrade compatible P320 Full-Size pistols to the X-Five configuration. It provides a higher grip with an extended beavertail, a deeper trigger guard undercut and a raised backstrap to aid in consistent hand placement and recoil management. The module ships with a removable grip weight and a removable magazine funnel (magwell) to support balance and faster reloads. Note that XSeries grip modules are compatible with newer P320 magazines featuring the circular SIG logo; Gen 1 magazines require modification to fit.
