Key Specifications
The USP45 Compact V1 .45 ACP features a 3.78-inch barrel mounted on a one-piece machined slide crafted from nitro-carburized steel with a choice of Hostile Environment blued or stainless steel finishes. The corrosion-proof, fiber-reinforced polymer frame provides exceptional durability while maintaining a lightweight profile. This configuration comes standard with two 8-round magazines featuring your choice of flat or extended floorplates. The DA/SA safety/decocking lever is positioned on the left side for natural thumb operation, and the ambidextrous magazine release ensures smooth, intuitive handling for shooters of all preferences.
Performance & Ballistics
Built for precision and velocity, the USP45 Compact V1 .45 ACP utilizes a polygonal bore profile that increases muzzle velocity, facilitates easier cleaning, and extends barrel longevity. The specially designed captive recoil spring assembly incorporates a polymer absorber bushing to manage recoil energy effectively, ensuring consistent accuracy and reduced felt recoil. The grooved target triggers deliver crisp, predictable breaks, while the gun’s convertible design allows configuration into any of nine distinct trigger/firing modes to match individual preferences or organizational requirements. The flared recurve trigger guard accommodates both standard and tactical shooting stances.
Safety & Operational Features
The HK USP45 Compact V1 .45 ACP incorporates Heckler & Koch’s patented Lock-Out Safety device, preventing accidental discharge during unintended handling. The no-snag bobbed hammer reduces printing under clothing for concealed carry applications. An extractor that doubles as a loaded chamber indicator provides tactile confirmation of a ready round. Universal mounting grooves integrated into the frame accept modern tactical accessories, and the contoured extended slide release enables positive manipulation with either hand.
Intended Use
