3 Gun Competition

3-gun competition is a shooting sport where competitors engage steel and paper targets using three different firearms — a rifle (typically an AR-15), a shotgun (semi-auto or pump), and a pistol — across timed stages that test speed, accuracy, and gear management. It’s one of the fastest-growing practical shooting disciplines in the country, and Impact Guns carries the rifles, shotguns, pistols, and accessories that competitive 3-gun shooters rely on.

What Is 3-Gun Competition?

3-gun is a practical shooting sport sanctioned by organizations including USPSA, 3-Gun Nation, and Multi-Gun matches at clubs nationwide. Competitors move through stages engaging targets at varying distances using a rifle, shotgun, and pistol in sequence. Stages are scored on time plus penalties, rewarding both accuracy and speed. Match formats vary — some emphasize close-range shotgun work, others feature long-range rifle stages out to 200+ yards — making gear selection and practice with all three platforms essential.

The 3-Gun Rifle: AR-15 Platform Dominates

The AR-15 in 5.56/.223 is the overwhelming choice for 3-gun rifle. Its adjustable stock, low recoil, and wide availability of competition-oriented components make it ideal for fast target transitions and accurate long-range shots. Popular builds use 16” or 18” barrels, flat-top uppers with LPVO scopes (1-6x or 1-8x), and tuned triggers in the 3–4 lb range. Brands like Daniel Defense, Aero Precision, and Ruger AR-556 are common starting points. See our AR-15 rifles category.

The 3-Gun Shotgun: Semi-Auto vs. Pump

Semi-automatic shotguns are the competitive standard for 3-gun — gas-operated or inertia-driven designs cycle faster than pump actions and allow a more consistent shooting cadence. The Benelli M2, Mossberg 940 Pro, and Beretta A300/A400 series are top choices. Extended magazine tubes (8+ rounds) and side saddles for spare shells are near-universal additions. Pump shotguns are allowed in most divisions and are the more affordable entry point, but semi-autos provide a measurable speed advantage at higher levels of competition.

The 3-Gun Pistol: Speed and Capacity

For the pistol portion of 3-gun, high-capacity 9mm pistols in USPSA-style divisions are most popular. The Sig Sauer P320, Glock 17/34, Springfield Echelon, and Staccato 2011-pattern pistols are all competitive choices. Trigger upgrades, extended magazine basepads, and red dot optics are common modifications. Capacity and reliable feeding under speed are the priority — most 3-gun pistol stages run 10–30 rounds.

Optics for 3-Gun

The rifle optic is the most impactful gear decision in 3-gun. A low-power variable optic (LPVO) in the 1–6x or 1–8x range covers both close-range transitions at 1x and accurate long-range shots at full magnification. The LPVO category includes competition-proven options from Vortex, Leupold, and Nightforce. For the pistol, a pistol red dot improves target acquisition speed significantly. Most top 3-gun competitors run optics on both the rifle and pistol.

Frequently Asked Questions

What guns do I need for 3-gun competition?
You need three firearms: a rifle (AR-15 in 5.56 is standard), a shotgun (semi-auto preferred), and a pistol (9mm high-capacity recommended). Most beginners start with whatever they already own and upgrade over time. Many clubs offer loaner gear or allow new shooters to participate with borrowed equipment for their first match before committing to a full setup.

What divisions exist in 3-gun?
Common 3-gun divisions include Tac Optics (optics allowed, limited modifications), Open (unrestricted), Heavy Metal (major calibers — .308 rifle, 12-gauge shotgun, .45 ACP pistol), and Tactical Irons (iron sights only). Division rules vary by match organization. USPSA Multi-Gun and 3-Gun Nation each have their own division structures. Check the specific match rules before selecting your equipment.

Is 3-gun a good sport for beginners?
Yes — most 3-gun matches welcome new shooters, and many clubs offer new shooter orientations. You don’t need competition-specific equipment to start. The sport rewards safe gun handling and consistent practice across all three platforms. Starting in a Tac Optics or stock division with standard equipment is the recommended path before investing in competition-specific modifications.
