The Remington Model 870 is a pump-action shotgun manufactured by Remington Arms Company, LLC. It is widely used by the public for sport shooting, hunting, and self-defense and used by law enforcement and military organizations worldwide.
Mossberg 500 is a series of pump action shotguns manufactured by O.F. Mossberg & Sons. The 500 series comprises widely varying models of hammerless repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, stock and forearm materials. Model numbers included in the 500 series are the 500, 505, 510, 535, and 590.
A sawed-off shotgun also called a sawn-off shotgun and a short-barreled shotgun (SBS), is a type of shotgun with a shorter gun barrel—typically under 18 inches—and often a shortened or absent stock. Despite the colloquial term, barrels do not, strictly speaking, have to be shortened with a saw. Barrels can be manufactured at shorter lengths as an alternative to traditional, longer barrels. This makes them easier to transport due to their smaller profile and lighter weight. The design also makes the weapon easy to maneuver in cramped spaces, a feature sought by military close quarters combat units, law enforcement SWAT team users, and home defense purposes. With modern pump action/magazine tube shotguns, the shorter barrel limits the magazine capacity of the weapon due to the magazine tube protruding beyond the barrel. Therefore, the magazine tubes are matched in length to the barrel, which causes a reduction in the number of shells that can be held in the magazine tube.
The Winchester Model 1897, also known as the Model 97, M97, or Trench Gun, was a pump-action shotgun with an external hammer and tube magazine manufactured by the Winchester Repeating Arms Company. The Model 1897 was an evolution of the Winchester Model 1893 designed by John Browning. From 1897 until 1957, over one million of these shotguns were produced. The Model 1897 was offered in numerous barrel lengths and grades, chambered in 12 and 16 gauge, and as a solid frame or takedown. The 16-gauge guns had a standard barrel length of 28 inches, while 12-gauge guns were furnished with 30-inch length barrels. Special length barrels could be ordered in lengths as short as 20 inches, and as long as 36 inches. Since the time the Model 1897 was first manufactured it has been used by American soldiers, police departments, and hunters.
The Saiga-12 is a 12-gauge shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named for the Saiga antelope. Like the Kalashnikov rifle variants, it is a rotating bolt, gas-operated gun that feeds from a box magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly.
The Ithaca 37 is a pump-action shotgun made in large numbers for the civilian, military, and police markets. It utilizes a novel combination ejection/loading port on the bottom of the gun which leaves the sides closed to the elements. Since shotshells load and eject from the bottom, operation of the gun is equally convenient for both right and left hand shooters. This makes the gun popular with left-handed shooters. The model 37 is considered one of the most durable and reliable shotguns ever produced.
A punt gun is a type of extremely large shotgun used in the 19th and early 20th centuries for shooting large numbers of waterfowl for commercial harvesting operations. These weapons are characteristically too large for an individual to fire from the shoulder or often carry by themselves, but unlike artillery pieces, punt guns are able to be aimed and fired by a single man from a mount. In this case, the mount is typically a small watercraft. Many early models appear similar to over-sized versions of shoulder weapons of the time with full-length wooden stocks with a normal-sized shoulder stock. Most later variations do away with the full-length stock--especially more modern models--and have mounting hardware fixed to the gun to allow them to be fitted to a pintle.
The Winchester Model 1912 is an internal-hammer, pump-action, shotgun with an external tube magazine. Popularly named the Perfect Repeater at its introduction, it largely set the standard for pump action shotguns over its 51-year high-rate production life. From August 1912 until first discontinued by Winchester in May 1964, nearly two million Model 12 shotguns were produced in various grades and barrel lengths. Initially chambered for 20 gauge only, the 12 and 16 gauge versions came out in 1913, and the 28 gauge version came out in 1934. A .410 version was never produced; instead, a scaled-down version of the Model 12 known as the Model 42, directly derived from scaled drawings of the Model 12, was produced in .410.
A coach gun is a modern term, coined by gun collectors, for a Double-barreled shotgun, generally with barrels from 18" to 24" in length placed side-by-side. These weapons were known as "cut-down shotguns" or "messenger's guns" from the use of such shotguns on stagecoaches by shotgun messengers in the American Wild West. They came in 10 and 12 gauge blackpowder.
The M26 Modular Accessory Shotgun System (MASS) is a developmental under-barrel shotgun attachment for the M16/M4 family of United States military firearms. It can also be fitted with a pistol grip and collapsible stock to act as a stand-alone weapon. It is replacing the current M500 shotguns in service.
The KS-23 is a Russian shotgun, although because it uses a rifled barrel it is officially designated by the Russian military as a carbine. KS stands for Karabin Spetsialniy, "Special Carbine". It is renowned for its large caliber, firing a 23 mm round, equating to 6.27 gauge using the British and American standards of shotgun gauges and approximately 4 gauge using the current European standards, making it the largest-bore shotgun in use today.
The Benelli M3 is a dual-mode shotgun designed and manufactured by Italian firearms manufacturer Benelli Armi SpA. The M3 holds a maximum of seven rounds and uses the proprietary Benelli semi-automatic system first showcased in the M1. The M3 is notable for allowing the user the choice of semi-automatic or pump-action operation. It is reliable and versatile, and popular with military and police forces as well as civilians.
