In case you live under a rock and only stumbled upon this How to Guide by accident, let me give you a quick rundown on what 3-Gun is. 3-Gun is a shooting competition that requires the shooter to use 3 guns (imagine that!) to complete a set course of fire in the fastest possible time. Competitors shoot rifles, pistols and shotguns at a multitude of target types from point blank range out to several hundred yards. One of the cool things about the sport of 3-Gun, unlike almost every other shooting sport, is that each course of fire is unique. You never get fatigued from repetitively shooting the same old thing every time!
