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 version 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 features an ergonomic grip design that includes changeable backstraps along with molded finger grooves that naturally position the user’s hand for optimal shooting. All HK45 pistol series (compact, full-size, Tactical models) are manufactured at HK’s American facility in Columbus, Georgia using American and German components.
