The 12-gauge shotgun is a broad family of shoulder-fired smoothbore firearms chambered for fixed shotgun shells. Modern 12-gauge guns span pump-action, break-action, and semi-automatic layouts, while documented conflict roles range from Ukrainian short-range counter-drone defense and Central African militia small arms to Islamic State recoveries; Haiti coverage is narrower because the cited reporting identifies gang-held pump-action shotguns without confirming gauge.
During the 2022 Haitian Gang Conflict, reporting from Port-au-Prince described armed gang members carrying pump-action shotguns alongside rifles and automatic weapons; the source supports shotgun possession and street presence but does not specify the gauge of those gang-held guns.
Conflict Armament Research reported that anti-balaka militias opposing Seleka forces were armed primarily with artisanal weapons, 12-gauge shotguns, and hunting rifles, and documented 12-gauge shotgun ammunition recovered from anti-balaka fighters and armed civilians in 2014.
Ukraine's defence ministry codified three Ukrainian 12-gauge pump-action shotgun modifications for the armed forces after they proved effective against Russian kamikaze drones; field reporting also describes Ukrainian soldiers carrying 12-gauge shotguns against drones.
Role detailsA Multinational Security Transition Command-Iraq delivery to Iraqi forces included 48 shotguns and 450,000 12-gauge shotgun rounds, including 200,000 slug rounds.
Role detailsConflict Armament Research documented 22 12-gauge shotguns recovered from Islamic State forces in Iraq and Syria during its 2014-2017 field investigations.
Role detailsThe 12-gauge shotgun page is a category-level record, so the strongest reader value comes from separating action families, ammunition links, and directly sourced conflict appearances. Pump-action examples dominate the military and security sources used here, but the broader 12-gauge class also includes break-action and semi-automatic designs.
Mossberg, Remington, and Winchester product pages document current 12-gauge pump-action examples with multiple barrel, chamber, and capacity configurations.

CAR, Ukraine, Iraq, and Islamic State rows are gauge-specific. The Haiti row is narrower because the cited reporting identifies gang-held pump-action shotguns but does not specify their gauge.

The 12-gauge designation covers a gauge family rather than one model lineage, so the main distinctions are operating system, chamber length, feed arrangement, and intended use.
| Variant | Configuration | Designation notes |
|---|---|---|
| Pump-action 12-gauge shotguns | Manual repeating shotgun | Representative current examples include Mossberg 590, Remington Model 870, and Winchester SXP product families offered as 12-gauge pump-action shotguns. Sources: 590 Shotguns, Model 870, SXP Black Shadow |
| Break-action 12-gauge shotguns | Hinged-barrel shotgun | Over-under and other break-action 12-gauge layouts remain common in sporting and field shotguns; Akkar's Open Country line is listed in 12-gauge with 2 3/4- to 3-inch chambers. Sources: Akkar Open Country Series |
| Semi-automatic 12-gauge shotguns | Self-loading shotgun | The Benelli M4 Tactical and Beretta 1301 Tactical families illustrate tactical 12-gauge semi-automatic configurations with 2 3/4- and 3-inch chambering. Sources: M4 Tactical Semi-Auto Shotguns, 1301 Tactical |
Army and Marine Corps guidance explicitly cover buckshot and other 12-gauge shotgun ammunition fired from 12-gauge shotguns.
| Ammunition | Ammunition type | Firing evidence |
|---|---|---|
 | Less-lethal round | Army range-safety guidance specifically discusses firing 12-gauge bean bag rounds from a 12-gauge shotgun, making this a strict shotgun-to-ammunition pairing. Sources: Range Safety |
 | Buckshot shotshell | Army range-safety guidance treats 12-gauge buckshot as shotgun ammunition, and Marine Corps deer-hunt guidance explicitly permits 00 or 000 buck shot in 12-gauge shotguns. Sources: Range Safety, Deer Hunt Bulletin |
 | Slug cartridge | Army range-safety tables include 12-gauge slug ammunition in 12-gauge direct-fire guidance, and an OSHA report describes a shotgun loaded with 12 gauge slug ammunition. Sources: Range Safety, Accident Report Detail |
 | Breaching round | Army ammunition guidance identifies the M1030 breaching round as fitting current standard military 12-gauge shotguns, including Mossberg 590 and Remington 870 shotguns, and Defense Technology describes it as a 12-gauge breaching shell used against locks and hinges.
