The Heckler & Koch HK45C is a compact hammer-fired pistol chambered in .45 ACP and configured for double-action and single-action operation. Its polymer frame includes interchangeable backstraps for a more adaptable grip, while the left-side decocking lever provides a controlled way to safely lower the hammer. White-dot front and two-dot rear sights offer a clear factory sight picture, and the compact dimensions make the HK45C well suited to duty, defensive, and concealed-carry applications.
