H&K HK45 V1 | .45 ACP | 4.46″ | 10+1 | HK 81001208

The Heckler & Koch HK45 V1 is a full-size semiautomatic pistol chambered in .45 ACP featuring a 4.46″ polygonal rifled barrel and a Flat Dark Earth finish. It uses a polymer frame with interchangeable backstraps for a customizable grip and an MIL-STD-1913 (Picatinny) accessory rail for lights or lasers. Controls are ambidextrous and the frame-mounted USP-style safety/decocking lever provides a positive stop and returns to the fire position after decocking. For an optic under $1,000 that pairs well, consider a low-profile red dot such as the Trijicon MRO for durable, quick target acquisition on duty or range use.
