Multigun, Multi Gun or Multi-Gun, often also called 2-Gun or 3-Gun depending on the types of firearms used, are practical shooting events where each of the stages require the competitor to use a combination of handguns, rifles, and/or shotguns[1] Multigun has a lot in common with ordinary IPSC/ USPSA single gun matches, and matches generally have courses of fire where the shooter must move through different stages and engage targets in a variety of different positions.
Multigun in its oldest form is arranged by the International Practical Shooting Confederation (IPSC) as Tournaments, but doesn't require the competitor to transition between firearms during the stage. Instead tournaments consists of separate Component Matches for each firearm type with a combined scoring in the end.
