3 Gun Started out as a Tactical combat type training deal with the old soldier of fortune matches back in the 80's. now its a nationally televised fast paced game with guns. It's all about shooting fast and accurate with cutting edge guns and gear.
If you're looking for firearms training that is bette Learned in a tactical class. What the action shooting sports like 3 gun, IDPA or USPSA will teach you is firearms manipulation under the stress that a timed competitive situation puts you in.
The LEO/MIL types I know that play the gun games all agree that competition makes you a better marksman which helps in real world situations.
Give it a try. You won't be disappointed!
