An issue with the use of starting pistols is that, since the report of the pistol is carried to the competitors at the speed of sound
Speed of sound
The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at , the speed of sound is . This is , or about one kilometer in three seconds or approximately one mile in five seconds....

, which takes about 3 milliseconds to travel one meter, positions nearest the starter hear the report a few milliseconds before further positions. This issue is exaggerated in races where the runners begin in a stagger, putting a significant distance between the nearest and furthest runners. To avoid this problem, the pistol is sometimes wired with a microphone that transmits the sound virtually instantaneously to loudspeakers directly behind each competitor.

With security after the September 11 attacks on the US becoming prevalent, causing issues with starting pistols, a trend developed to use electronic starting systems that do not use pistols, but use obviously toy weapons that are wired to the timing system. When the starter presses the button, they emit a signal to play a simulated gunshot that is broadcast to loudspeakers behind each lane, show a flash, emit simulated smoke, and start the timing clock. Many venues have switched to the new format.

Criminal use

Pistols converted to fire blanks only can be converted back to fire live ammunition; some pistols designed to fire blanks can be modified to fire live ammunition. Some pistols manufactured specifically to fire blank cartridges are designed to resemble real weapons. Criminals use such weapons both to intimidate due to their appearance, and as actual firearms.
