IPSC shooting combines accuracy, speed and power in different courses of fire. The scoring system is designed to reward each of the three attributes equally. Competitors use centerfire handguns in large calibres (9mm/.38 special minimum) and shoot full-power loads. Maximum points are awarded for shots in the “A zone”, fewer points are awarded for shots outside the “A zone”. Competitors using “minor” power loads lose more points than competitors using “major” power loads. Handguns and magazines are carried in holsters and magazines pouches attached to a belt.
