The HK45 Tactical Black Gas Blowback Pistol is a variation of the standard HK45pistol, now available with a silencer compatibility feature. This model enhances the traditional HK45 by incorporating a tactical silencer that attaches to its hybrid metal and resin outer barrel, combining the unique experience of gas blowback with silencer functionality. It maintains the live firing and operational performance of the original HK45 but includes updated features like new sight configurations and an ambidextrous safety and decocking system.
