The Heckler & Koch HK45 Compact Tactical is a hammer-fired .45 ACP pistol built for discreet carry, duty use, and suppressed applications. Its double-action/single-action operating system combines a longer initial trigger pull with a lighter single-action follow-up. The pistol features a 4.57-inch threaded barrel with an M16x1 left-hand thread pitch, allowing compatible muzzle accessories to be installed. Factory night sights support visibility in low-light conditions, while the polymer frame and interchangeable backstraps help users tailor the grip to their hand. A manual safety and left-side decocking lever provide flexible controls, and the pistol accepts 10-round magazines for a 10+1 capacity.
