# HK 45 - Guns For Sale

The HK45 is a full-size semi-automatic pistol chambered in .45 ACP, designed for tactical use, self-defense, and duty carry. The polymer frame is reinforced with steel inserts; interchangeable backstraps allow grip sizing for different hands. A low bore axis reduces muzzle rise. The pistol is available with a DA/SA trigger and decocker, or with the HK LEM (Law Enforcement Modification) trigger for a consistent pull. Controls are ambidextrous. A Picatinny rail accommodates lights and lasers, and a corrosion-resistant finish handles harsh conditions.
