BRÜGGER & THOMET MP9-INSPIRED SUBMACHINE GUN

This SMG's design directly echoes the Brügger & Thomet MP9, a real Swiss-made personal defense weapon known for its compact size and high rate of fire, favored by close-protection and special-response units in real life for how easily it conceals under clothing. Its appearance in GTA 6 trailer footage puts it alongside several other real-world-firearm-inspired SMGs Rockstar has confirmed, suggesting the game's close-range arsenal leans toward recognizable modern platforms rather than purely fictional designs this time around.
