Heckler & Koch HK HK45 Tactical .45 ACP 10+1 81001117

Originally developed as part of the U.S. military’s Joint Combat Pistol program in 2005-6, the HK45 Tactical model is the threaded barrel variant of the HK45 and comes standard with a threaded barrel and adjustable Truglo high profile sights that are suitable for use with or without suppressors. The sights are made exclusively for HK.

The full-size HK45 Tactical (HK45T) model uses an ergonomic grip design that includes changeable backstraps together with molded finger grooves that instinctively position an operator’s hand for optimum shooting. All HK45 pistol series (compact, full-size, Tactical models) are made at HK’s American manufacturing facility in Columbus, Georgia using American and German components.

During the 1960s, Heckler & Koch perfected the famous polygonal profile barrel technology. Conventional lands-and-grooves rifling allow propellant gasses to escape around the front of the bullet as it is fired from the barrel muzzle. A polygonal bore profile effectively seals propellant gases behind the bullet—increasing bullet velocity. An added benefit of a polygonal barrel is its resistance to wear. A polygonal barrel will normally outlast a conventional “lands-and-grooves” barrel by thousands of rounds. Polygonal barrels were one of the many radical design elements used on the HK P7 series pistol and this same breakthrough technology is present on all current HK handguns.

A radical new material used on the P9S pistol in the late 1960s, advanced polymers were soon used as major components and assemblies on a variety of HK products — including the receivers of MP5s in the 1960s. HK polymer molding technology led to the introduction of another synthetic framed HK handgun, the futuristic-looking VP70. Heckler & Koch pioneered the use of polymers more than fifteen years before competing firms. Today, HK remains a technology leader in the use of innovative and high-strength polyamides.
