A 3-gun competition is just that 3 guns.
You use a rifle, a pistol & a shotgun.
It's probably the most fun you can have with your clothes on & even then it comes in a very close second.
Most stages will only be 2 guns, say a shotgun/pistol stage but there are times when all 3 will be used on 1 stage. The matches we have at OKC Gun Club usually consist of 4-5 stages. We'll usually wrap up around 3:00p starting at around 10:00a. The round count will vary from match to match. Last monthe the minimum round count (not counting misses) was about 125 Rifle, 30 Bird, 3 Buck, 3 Slug, and 40 pistol. There are videos of 3 gun on Jesse's you tube channel, Check those out & you'll be frothing at the mouth for some 3 gun action. As said many times, don't let gear keep you from participating. Lot's of us have extra for those that need it.
