The 3.94-inch cold-hammer-forged barrel is threaded M16 × 1 LH and features an O-ring lockup for enhanced accuracy and repeatable muzzle alignment when running suppressors or muzzle devices. Polygonal rifling maximizes velocity and barrel life while easing maintenance.
A nitro-carburized slide with deep roll marks houses suppressor-height tritium sights that offer a 6-inch sight radius and a clear sight picture over most muzzle devices. The slide’s BF date code and Ulm proof mark verify 2015 German barrel manufacture paired with U.S. frame assembly.
The fiber-reinforced polymer frame keeps weight down and includes an integral MIL-STD-1913 rail for lights or lasers. Ambidextrous paddle-style magazine releases, slide releases, and a Variant 1 safety/decocker give both right- and left-handed shooters full control.
This DA/SA pistol ships with two 10-round magazines and maintains the high-reliability reputation of the HK45 platform, making it a solid choice for suppressed carry, range work, or collection.
