High Quality Content by WIKIPEDIA articles! A racegun is a type of handgun, shotgun, or rifle that has been modified for accuracy, speed, and reliability. Used primarily in USPSA/IPSC and similar styles of competition, raceguns are typically based on common guns and modified to function the best within a certain set of rules, such as weight, size, and capacity requirements. Typical modifications include a match-grade barrel fitted with a recoil compensator, electronic optical sights, match-grade hammer and sear, a tuned trigger, and "skeletonizing" (cutouts to reduce weight.) Depending upon the competition requirement, some raceguns are modified with reduced-weight recoil springs to allow the use of lightly-loaded ammunition that is just barely powerful enough to cycle the gun's mechanism, in order to reduce recoil and permit a faster rate of fire. To prevent this, certain competitions such as IPSC and USPSA require ammunition to meet specific power factors.
