The hk45 compact is well-suited for personal defense use, and it has a da/sa trigger system with a safety/decocking lever on the left side.The hk45c features a "slim-line" grip, shorter barrel and slide than the standard hk45, but it is otherwise functionally identical to the standard hk45.The hk45c can be fitted with a threaded barrel for use with a muzzle-mounted sound suppressor.The internal mechanical recoil reduction system reduces the recoil forces imparted to the weapon and shooter by as much as 30%, improving shooter control during rapid firing and increasing component service life.This pistol features a mil-std 1913 picatinny rail, ambidextrous controls with dual slide releases, enlarged magazine release, low profile drift-adjustable 3-dot sights, polygonal rifling for longer barrel life and increased accuracy, and two magazines.Frame Finish: BlackType: PistolAction: DA/SACaliber: 45 ACPBarrel Length: 3.94"Capacity: 8+1Safety: Decocker/ManualGrips: Black Interchangeable BackstrapSight Configuration: 3-Dot Adjustable Low ProfileWeight: 25.30 ozFrame Material: PolymerBarrel Type: ThreadedSlide Description: SerratedCase Type: HardSight Style: AdjustableBarrel Length Range: 3.00" to 3.99"Weight Range: 16.00 oz to 31.99 oz
