Starting pistol

A starting pistol or starter pistol is a blank handgun^[1] or, more recently, an electronic toy gun or device with a button connected to a sound system that is fired to start track and field races as well as some competitive swimming races. Traditional starter guns cannot fire real ammunition without first being extensively modified: Blank shells or caps are used to prevent expelling projectiles,^[1] and only a small amount of smoke can be seen when shot. In most places, trying to modify the replica is illegal.^[2]

Starting pistols may also include modified versions of standard pistols incapable of firing bullets, most commonly achieved by welding an obstruction into the barrel. This is less common nowadays, especially in Western countries. When electronic timing is used, a sensor is often affixed to the gun, which sends an electronic signal to the timing system upon firing. For deaf competitors or for modern electronic systems, the electronic toy gun sends off a light signal, with some events using a light system.
