The HK45C Tactical threaded barrel is a factory-original replacement for the HK45 Compact Tactical, built to the exact specs of the part that came in your pistol. It measures 4.57 inches, wears a black finish, and comes threaded 16×1 metric left-hand so you can mount a suppressor, flash hider, or compensator without hunting for adapters. If you already own the standard HK45C and want to add threads, or you just want a spare tactical barrel on hand, this is the OEM route.
This is a true drop-in part. No gunsmithing, no fitting, no filing. Pop your slide apart, swap the barrel, and you are back together in a couple of minutes. Because it is made using HK's famous cold hammer forging process with polygonal rifling, you get the same accuracy and longevity the platform is known for, plus a polished feed ramp that keeps a wide range of .45 ACP loads cycling smoothly.
Read this part closely before you order. This barrel is cut specifically for the HK45 Compact and its Tactical variant. It will not fit the full-size HK45, and it will not drop into any USP or USP Compact pistol, since those use a different thread and dimensions. If your pistol is an HK45C or HK45CT, you are in the right place.
The left-hand 16×1 thread is the standard HK uses across its .45 tactical lineup, so most .45-rated cans and muzzle devices built for that spec will thread right on. Running a suppressor tames the report and helps with control, which makes for a much more pleasant range session. Being a genuine HK component, this barrel goes through the same quality control and headspacing as original equipment, so you can trust it to run right out of the box.
It is made specifically for the HK45 Compact and the HK45C Tactical (HK45CT). It will not fit the full-size HK45, and it will not work in any USP or USP Compact pistol since those use different dimensions and threading. If you own an HK45C or HK45CT, this is a direct drop-in.
It is threaded 16x1mm metric with a left-hand pitch, which is the standard HK runs across its .45 tactical barrels. That means most .45-rated suppressors, flash hiders, and compensators built for this spec will thread right on. Just double-check that your muzzle device or can is set up for 16×1 LH.
Factory HK barrels typically ship as just the barrel, without a thread protector or O-ring. HK sells a matching .45 thread protector cap separately if you want to keep the threads covered when you are not running a device. It is a cheap add-on and worth grabbing to protect those threads.
No. This is a true drop-in part that installs in a couple of minutes with a basic field strip. Since it is a genuine HK component machined to factory specs, headspacing and lockup are handled at the factory, so there is no fitting required.
