An gun-silencer (1) for mounting at the muzzle (9) of a gun-barrel comprises a baffle-free, generally-cylindrical gas-expansion chamber (2) intermediate a proximal entry-port (6) and a distal exit-port (7) both aligned with said gun-barrel when mounted thereon, the internal end walls of said expansion chamber being divergent from the entry-port at its proximal (3) end over a curve whose ends subtend an angle not greater than 90 DEG , and convergent on the exit-port (6) at its distal end (7) over a curve whose ends subtend an angle greater than 90 DEG . |
