The HK45 Tactical features a threaded barrel for suppressed use and high profile sights. The barrel uses an O-Ring for improved slide to barrel lockup and enhanced accuracy. The HK45 Tactical utilizes a proprietary internal mechanical recoil reduction system that uses a flat recoil spring in conjunction with a polymer bushing to reduce recoil forces and prolonging component service life.
The V7 firing mode features HK’s enhanced double action only “LEM”(Law Enforcement Modification) mode. This mechanism improves trigger performance and reduces the double action only trigger pull.
