Notes
M.O.D. = Modular Off-Duty. The 941 g figure is the published weight with magazine (~33.2 oz). Configurable via SIG's modular FCU - the grip weight and magwell are removable to tune balance and concealment.
Background
Built around SIG's serialized fire-control unit, the M.O.D. leans hard into the 'one gun, many guns' idea - drop in or pull out a grip weight, magwell and comp to swing the same pistol between a heavy range build and a slim off-duty carry.
