The Heckler & Koch HK45T V1 is a tactical variant of the HK45 series chambered in .45 ACP, equipped with a threaded barrel, polymer frame, and an accessory rail for lights or lasers. The design includes user-changeable backstraps and is supplied with two magazines. It emphasizes controllability and modular ergonomics for users who prefer a full-size .45 platform.

For an optic under $1,000 that pairs well with this pistol, consider a Trijicon RMR or a comparable compact red-dot; these footprints retain sight radius and are robust enough for regular range use.
