All usps feature a fiber-reinforced polymer frame stiffened by stainless steel inserts at areas subject to stress and friction.The control lever, a combination safety and decocking lever, is frame mounted and quickly accessible, unlike the slide-mounted safeties.Using a modified browning-type action with a special patented recoil reduction system, the usp recoil reduction system reduces recoil effects on pistol components and also lowers the recoil forces felt by the shooter.The usp recoil reduction system is insensitive to ammunition types and requires no special adjustment or maintenance.This v1 model has a double action/single action with safe position, night sights, and comes with with three 13-round magazines.Frame Finish: BlackType: PistolAction: SA/DACaliber: 40 S&WBarrel Length: 4.25"Capacity: 13+1Safety: Manual, DecockerGrips: Black PolymerSight Configuration: NightWeight: 28.96 ozFrame Material: PolymerBarrel Type: Cold Hammer-Forged Polygonal RifledSlide Description: Serrated Black SteelSight Style: NightBarrel Length Range: 4.00" to 4.99"Weight Range: 16.00 oz to 31.99 oz
