A starter pistol is a type of firearm designed to emit a loud noise without firing a projectile. It is commonly used in sporting events, such as races, to signal the start of the competition. The sound produced by the starter pistol alerts participants and spectators that the event is beginning. These pistols typically use blank cartridges, which create a loud bang but do not contain bullets. Starter pistols are often seen in track and field events, where they help ensure a fair start. They are distinct from regular firearms and are not intended for self-defense or hunting purposes.
