    The HK45 Compact is a proven .45 ACP defensive pistol that blends manageable size with HK’s robust engineering.

It comes with two 8-round steel magazines, the factory case, manual, and a spare backstrap, with a bright, clean bore and good overall condition.

    What’s Included
    • HK factory hard case
    • HK45 / HK45 Compact Operator's Manual
    • Two 8-round steel magazines
    • Spare interchangeable backstrap insert

    The HK45 Compact runs a DA/SA, recoil-operated, modified Browning tilting barrel system with an exposed hammer. Its frame-mounted safety/decocker supports both cocked-and-locked carry and safe decocking, offering versatile carry and administrative handling options.

    The 3.90 in cold hammer-forged barrel uses right-hand polygonal rifling for durability and easy maintenance. Sights are fixed iron with a single-dot front post and a low-profile rear notch, paired with a 6.04 in sight radius for a clear and consistent sight picture.

    Dimensions are well-suited to a compact .45 ACP: overall length 7.24 in, height 5.51 in, width 1.54 in. Unloaded weight without a magazine is 28.57 oz. Capacity is 8+1, and the pistol accepts both 8-round HK45C and 10-round HK45 magazines.

    Controls are user-friendly and ambidextrous where it matters, including the paddle-style magazine release. The polymer frame has stippled grip inserts and interchangeable backstraps to tailor fit. An integral 4-slot MIL-STD-1913 rail under the dust cover accommodates compatible accessories.

    The slide and metal components wear HK’s Hostile Environment finish. This example includes two 8-round steel magazines, the factory hard case, and the original operator’s manual, along with a spare backstrap insert.
