If the name didn't already give it away, this sport involves three different firearms. A rifle, pistol, and a shotgun. The equipment will vary among shooters but 3-gunners typically start with a AR-15 style rifle (or any semi-automatic rifle in .223), 9mm pistol, and semi-automatic or pump 12 gauge shotgun. The event may require the competitor to use and transition between a combination of rifles, handguns, and shotguns or other types of firearms, on several different stages. 3 Gun has a lot in common with ordinary IPSC USPSA 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.
3 Gun competitions make skeet shooting look like tiddlywinks and CMP competition look like croquet. If you want some fast-paced fun, try one of the country’s fastest-growing shooting sports. 3 Gun!
