HECKLER & KOCH MP5/40-INSPIRED SUBMACHINE GUN

This SMG's design echoes the Heckler & Koch MP5/40, a real submachine gun chambered in .40 S&W and adapted from H&K's iconic MP5 platform, historically favored by law enforcement units for its accuracy and controllability at close range compared to lighter, faster-firing designs. Its appearance in GTA 6 trailer footage places it alongside several other real-world-firearm-inspired SMGs Rockstar has confirmed, part of a close-range arsenal that leans more toward recognizable tactical platforms than the more exaggerated, fictionalized guns of earlier GTA entries.
