A service pistol is any handgun issued to military personnel or law enforcement officers. Typically service pistols are revolvers or semi-automatic pistols issued to officers, non-commissioned officers, and rear-echelon support personnel for self defense, though service pistols may also be issued to special forces as a backup for their primary weapons. Pistols are not typically issued to front-line infantry.Before firearms were commonplace, officers typically carried swords instead.
Air Pistol is an Olympic shooting event governed by the International Shooting Sport Federation (ISSF). It is similar to 10 metre air rifle in that it is shot with 4.5 mm (or .177) caliber air guns at a distance of 10 metres (11 yards), and the programme consists of 60 shots within 75 minutes for men, and 40 shots within 50 minutes for women. If Electronic Scoring System (EST) is not available, additionally 15 minutes for men and 10 minutes for women are added to the time limit. Preparation and sighting time of 15 minutes is the same for both men and women. It is also similar to 50 metre pistol despite the shorter distance and the use of air guns, and most top-level male shooters compete in both events.
There are some restrictions on the pistol, and it must be operated by one hand only from a standing, unsupported position. The shooter decides his or her own tempo as long as the maximum time is not exceeded, but in the final round for the top shooters, separate commands are given for each shot so that the audience may follow the progress of the standings.
The major competitions are the Olympic Games every four years and the ISSF World Shooting Championships every four years. In addition, the event is included in the ISSF World Cup and in continental championships, as well as in many other international and national competitions. It is an indoor sport, and on the highest level electronic targets are used instead of the traditional paper targets.
