Heckler & Koch
The HK45 is a serious defensive and competition pistol, and adding a suppressor or other muzzle device transforms its capabilities. This H&K replacement barrel threads your HK45 for sound suppression, flash hiders, or compensators—a straightforward upgrade path when you're ready to run modern muzzle attachments. Built with H&K's exacting tolerances and finished in blue, it's a factory-quality spare that handles the rigors of duty or sport use.
Left-hand threaded at 16×1.0 mm, this barrel mates directly to HK45 pistols and provides the interface you need for threaded muzzle devices. At 5.20 inches long, it maintains the HK45's original ballistics and ergonomics while opening up your suppressor and accessory options. Whether you're building out a host pistol or keeping a spare on hand, this is straightforward, no-compromise engineering.
Installation requires basic armorer skills or a gunsmith's help, and swapping barrels is one of the cleanest ways to adapt a quality service pistol without permanent modifications. If you run an HK45 and suppression or muzzle control is on your roadmap, this threaded barrel is the foundation piece that makes it possible.

This barrel is designed for HK45 pistols. Confirm your exact model before ordering; if you own an HK45 or HK45 Tactical, this barrel will fit.
The 16×1.0 mm left-hand thread accepts any suppressor, compensator, flash hider, or muzzle device designed for that specification. Check your chosen muzzle device's thread pattern to ensure compatibility.
Barrel replacement requires field-stripping and basic armorer knowledge. If you're comfortable with pistol maintenance, you can do it yourself; otherwise, a gunsmith can install it quickly.
