    The HK45 Tactical V1 is a full-size .45 ACP with DA/SA operation and HK's V1 manual safety/decocker. It features ambidextrous slide releases and bilateral safety/decocker levers, plus an extractor-based loaded chamber indicator, firing pin block, and disconnector.

    Its 5.11 in cold hammer forged barrel is extended and threaded M16x1 LH, includes an accuracy O-ring, and uses polygonal rifling. A knurled thread protector is included. The left-hand metric thread pattern is uncommon among U.S. .45-caliber accessories.

    Sight configuration is set up with a tall front sight with a luminous dot, while the rear sight has been replaced by an ADE Helios micro red dot using a dovetail/plate mount. A multi-port compensator is installed on the threaded muzzle, and an elongated rail-mounted cover/extension is fitted to the dust-cover rail.

    The polymer-framed pistol has a black finish and HK45-pattern grip with interchangeable backstraps. A MIL-STD-1913 accessory rail with a single cross-slot is molded into the frame. Capacity is 10+1, and the package includes two 10-round steel magazines. The pistol is German-made and bears DE proof marks.
