Depending on the match format, the competitor may be required to shoot as many as 90 rounds using as many as three different handguns. Each shot scores a maximum of 10 points. Hence, a one-gun competition is often referred to as a "900" whereas a three-gun competition is a "2700". A shorter form is the National Match Course consisting of a single Slow Fire, a Timed and a Rapid Fire target, 30 shots for a maximum score of 300. Single gun competitions using only the rimfire pistol are common, as they provide an inexpensive entry into the sport.
