A simulated weapon includes a pressure switch within the simulated weapon's barrel. The pressure switch responds to pressure changes within the weapon barrel to activate a light emitter. In response, the light emitter emits a beam of light that simulates weapon fire by indicating the aim of the simulated weapon. Pressure changes within the barrel are induced by a conventional air cartridge that emits a blast of air when struck by the firing pin of the simulated weapon. The user can thus produce the simulated fire by activating the simulated weapon's trigger to trip the hammer and drive the firing pin into the air cartridge. In another embodiment, the simulated weapon activates a nonlethal pyrotechnic round. Simulated fire is produced in response to detection of the recoil, force, or pressure change produced by the pyrotechnic round. The simulated weapon may be a pistol, rifle or any other conventional hand held weapon.
