A replacement handguard on the Beretta PMX improves the surface for your support hand, and may add M-Lok slots for a hand stop that locks your forward grip position in place across draws and transitions. The PMX is a PCC used in IPSC PCC competition, where stage movement is frequent and consistent support hand placement is a direct input to target transition speed and accuracy. The handguard is the primary variable that determines where your support hand sits on the gun.
Confirm PMX-specific forend compatibility on the individual product page before ordering.
