Some info
The sport is known as "practical shooting" which requires the participant to blend accuracy, speed and power.
IPSC stands for International Practicle Shooting Confederation. Also has branches that include rifle & shotgun, and some times you will see 3 gun compititions where you use all 3.
From their website:
"IPSC athletes must blend accuracy, power, and speed into a winning combination. Handgun targets are 57 centimeters by 45 centimeters with a 15 centimeter center representing the "A zone" or bullseye.
Most shooting takes place at relatively close distances, with rare shots out to 50 meters. Hitting a 15 centimeter zone might seem easy to an experienced pistol shooter, but in IPSC only full power handguns are used (9mm or larger).
Mastering a full power handgun is considerably more difficult than shooting a light recoiling target pistol, especially when the competitor is trying to go as fast as possible. Time is a key factor. Scores are divided by the time taken to achieve them, adding to the challenge."
