H&K HK45C Tact V1 | .45 ACP | 4.57″ TB | 10rd | 81001115

The Heckler & Koch HK45C Tactical V1 is a compact, service‑grade .45 ACP pistol configured with a 4.57″ threaded barrel, adjustable high‑profile sights, and a polymer frame. The V1 model uses a DA/SA trigger system with a manual safety/decocking lever on the left side and ships with two 10‑round magazines and interchangeable backstraps for a tailored grip. This pistol suits precision range work and duty/backup carry where a compact .45 ACP is preferred; an optic such as the Holosun 507C (priced well under $1,000) pairs well for fast target acquisition on this platform.

The HK45C Tactical V1 combines a compact footprint with service‑oriented features: a threaded barrel for suppressor or accessory use, high‑profile adjustable sights for co-witness or enhanced sighting, and a slim grip profile for improved ergonomics. Its DA/SA controls and manual safety/decocker provide multiple carry and handling options without sacrificing consistency at the range. The included backstraps and two 10‑round magazines make it ready for immediate use in training or duty scenarios.

Owners commonly praise the HK45C for its slim grip ergonomics and the proprietary O‑ring barrel design that contributes to consistent barrel‑to‑slide lockup and strong accuracy for a compact .45 ACP. These traits make it a practical choice for shooters who want a compact, well‑engineered pistol with serviceable controls and accessory readiness.
