A revolver is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers for firing. Because most revolver models hold up to six cartridges, before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns.
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
Magnum Research Inc. (MRI) was an American privately held corporation based in Fridley, Minnesota which manufactured and distributed firearms. The majority owners, Jim Skildum and John Risdall, had been with the company since its founding in 1979.
A semi-automatic pistol is a handgun that automatically ejects and loads cartridges in its chamber after every shot fired. Only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset.
A lever action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, fully automatic, and/or burst mode actions. A firearm using this operating mechanism is colloquially referred to as a levergun.
The .50 Action Express (AE) (12.7×33mmRB) is a large-caliber handgun cartridge, best known for its usage in the Desert Eagle. Developed in 1988 by American Evan Whildin of Action Arms, the .50 AE is one of the most powerful pistol cartridges in production.
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge.
A breechblock is the part of the firearm action that closes the breech of a breech loading weapon before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge.
The .440 Cor-Bon is a large-caliber handgun cartridge, first produced by Cor-Bon in 1998. Although it looks similar to a .357 SIG, this cartridge was designed after being necked down from an existing cartridge, the .50 AE to accept a .44-caliber (10.89 mm) bullet. This is fairly typical in the wildcat cartridge industry.
A rim is an external flange that is machined, cast, molded, stamped, or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge.
The Wildey is a gas-operated, double-action or single-action pistol designed by Wildey J. Moore. It was designed to fire several high-pressure proprietary cartridges including the .45 Winchester Magnum and the .475 Wildey Magnum. They are currently being produced by USA Firearms Corp.-Wildey Guns of Winsted, Connecticut.
The Colt Model 1900 is a short-recoil operated "self-loading", or semi-automatic .38 caliber handgun introduced by Colt's Manufacturing Company at the turn of the 20th century. The M1900 was the first firearm to be chambered in .38 ACP and was the first handgun to utilize short-recoil operation.
Break action is a type of firearm action in which the barrel(s) are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barreled shotguns, double-barreled rifles, combination guns, and are commonly found in single shot pistols, rifles, shotguns, including flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions.
The Grizzly Win Mag pistols were conceived, invented, designed, engineered and developed in the 1980s by the sole inventor, Perry Arnett, who licensed his patent for an interchangeable caliber semi-automatic pistol to L.A.R. Manufacturing Inc. Perry Arnett's designs were initially flawed and were improved upon by Heinz Augat. The L.A.R. Grizzly was the most powerful semi-automatic pistol ever commercially produced after the Desert Eagle.
The Marlin Model 1894 is a lever-action repeating rifle introduced in 1894 by the Marlin Firearms Company of North Haven, Connecticut. At its introduction the rifle came with a 24-inch barrel and was chambered for a variety of rounds such as .25-20 Winchester, .32-20 Winchester, .38-40, and .44-40. Variants in other chamberings remain in production today.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
The .41 Action Express is a pistol cartridge developed in 1986 to reproduce the performance of the .41 Magnum police load in semi-automatic pistols.
The Mauser M 98 are a series of currently (2020) produced bolt-action hunting rifles. The production of the controlled round feed Mauser 98 bolt action system for the German military ceased at the end of World War II in 1945. The new Mauser M 98 and M 98 Magnum rifles for civil users are in production since 1999 in Isny im Allgäu, Germany by Mauser Jagdwaffen GmbH, according to original drawings of 1936 and the respective Mauser patents. Mauser Jagdwaffen GmbH is a subsidiary of SIG Sauer.
The .429 DE (10.9x33mmRB) is a cartridge introduced in 2018 by Magnum Research for the Desert Eagle line of handguns.
