• The six ISSF shooting events with pistols (four Olympic events plus two events not included in the Olympics program but are contested in World Cups and World Championships), its roots date back to the first modern Olympic Games in 1896, consist of both precision slow-fire and rapid-fire target shooting from distances of 10, 25, and 50 meters.The pistols are unique in appearance compared to normal guns and each events has its own pistols designed specifically for the job. Shooters must use one hand only to shoot at small “bullseye” target downrange. In the UK (except for Northern Ireland), it is no longer possible to practice for some of the Olympic events following the Firearms (Amendment) (No. 2) Act 1997, legislation brought in after the Dunblane Massacre.
• The CISM Rapid Fire match is similar to the ISSF 25 m Rapid Fire Pistol event.
• NRA Precision Pistol, also called conventional pistol shooting, is a bullseye shooting where up to 3 handguns of differing calibers are used. Its history is almost as old as ISSF events. Shooters must fire the pistol one-handed at 6- and 8-inch bullseye targets placed 25 and 50 yards downrange respectively.
• Precision Pistol Competition (PPC), was originally a police shooting program started in 1960 by the National Rifle Association.
