NRA conventional pistol competition consists of firing slow, timed, and rapid fire. This is done at 50 and 25 yards outdoors and almost exclusively at 50 feet indoors. Generally an outdoor match will consist of 20 shots, slow fire at 50 yards (two 10-shot strings, 10 minutes per string), 20 shots, timed fire at 25 yards (four 5-shot strings, 20 seconds per string), 20 shots, rapid fire at 25 yards (four 5-shot strings, 10 seconds per string), and the National Match Course (10-shots slow fire at 50 yards, 10-shots timed fire (two 5-shot strings), and 10-shot strings (two 5-shot strings). This match consists of 90 shots for a possible aggregate total of 900 points. For a 2700 aggregate this match is fired once with each gun: .22 caliber rimfire, center fire, and .45 caliber. Many match programs call for only one or two guns, that is a 900 or 1800 aggregate.
Most indoor tournaments are fired with .22 caliber rimfire only for a 900 aggregate. However, some indoor matches use all guns for a complete 2700 aggregate.
