Branded Shrewsbury, the Grenade Launcher is based on the Milkor MGL, a revolver-style launcher that holds several 40mm rounds. It clears rooms and wrecks vehicles with area damage rather than pinpoint hits. This is a heavy weapon you break out for chaos, not for a quiet approach.
Heavy weapons like this usually sit behind serious progression or a special unlock rather than an early counter buy, though a gun store in the Ammu-Nation mold is the likely base. Rockstar has not detailed GTA 6 gun shops, so this remains a best guess.
