A double-barreled shotgun is a break-action shotgun with two parallel barrels, allowing two single shots to be fired in quick succession or simultaneously.
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 also commonly called six shooters.
A semi-automatic firearm, also called a self-loading or autoloading firearm, is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
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.
Tippmann is an American manufacturer of paintball markers and paintball equipment, including military simulation (MilSim) kits. A related company, Tippmann Industrial Products manufactures manual and pneumatic heavy-duty sewing machines primarily used for leather, other leather-related equipment, and some industrial products. Originally a family-owned business run from Fort Wayne, Indiana, in 2004 Dennis Tippmann Sr. sold a majority ownership stake to Summit Partners, a private equity firm. Tippmann designed one of the first automatic markers, the use of refillable air systems in place of 12 gram cartridges, the "Cyclone Feed" system, the "Flatline" barrel, and the Tippmann C-3, the first propane-powered marker.
An automatic firearm is an auto-loading firearm that continuously chambers and fires rounds when the trigger mechanism is actuated. The action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition round into the chamber, and then igniting the propellant and discharging the projectile by delivering a hammer or striker impact on the primer.
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated, but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were almost exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets.
Double action refers to one of two systems in firearms where the trigger both cocks and releases the hammer.
In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface incorporated into the trigger. Sear mechanisms are also frequently employed in archery release aids.
Wassenaar Arrangement Semi-automatic Rifles are a line of rifles sold in the United States by Century International Arms. The rifles are manufactured in Romania by the Cugir Arms Factory and are a semi-automatic variant of the Pistol Mitralieră model 1963/1965, a Romanian licensed derivative of the Soviet AKM assault rifle. Century imports them and modifies them in order to comply with national legislation before sale to the general public via licensed traders. The WASR series takes its name from the 1996 Wassenaar Arrangement, a multilateral export control regime to monitor and limit the proliferation of certain conventional weapons and dual-use technologies.
The Thunder 9 is a full-size semi-automatic handgun manufactured by Bersa at the Ramos Mejia production plant in Argentina. It is also sold under the name Firestorm or FS 9.
The Spyker C8 is a sports car produced by the Dutch automaker Spyker Cars since 2000. The design takes visual cues from the 1999 Spyker Silvestris V8 concept car but with changes to the proportions.
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy.
The Smith & Wesson Model 39 is a semi-automatic pistol developed for the United States Army service pistol trials of 1954. After the Army abandoned its search for a new pistol, the Model 39 went on the civilian market in 1955 and was the first of Smith & Wesson's first generation semi-automatic pistols. A modified version saw limited use with Naval Special Warfare units as the Mk 22 Mod 0.
The Can-Am Spyder ("Spyder") is a three-wheeled motorcycle manufactured by Can-Am motorcycles, a division of Bombardier Recreational Products. The vehicle has a single rear drive wheel and two wheels in front for steering, similar in layout to a modern snowmobile. The Spyder uses an ATV-like chassis. The manufacturer refers to it as a "roadster," but in technical terms, it is more of what has been traditionally called a trike.
In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling.
A motorcycle transmission is a transmission created specifically for motorcycle applications. They may also be found in use on other light vehicles such as motor tricycles and quadbikes, go-karts, offroad buggies, auto rickshaws, mowers, and other utility vehicles, microcars, and even some superlight racing cars.
The Zastava PAP are a series of Serbian sporting rifles based on the Zastava M70 and Zastava M77B1.
