TERM DEFINITION
  
Safety
Device that blocks the firing operation of a firearm.
Scope
A telescopic sight, commonly called a scope, is an optical device used to give additional accuracy using a point of aim for firearms, airguns and crossbows.
Semi Automatic
A type of firearm which, utilizing some of the recoil or some of the expanding-gas energy from the firing cartridge, cycles the action to eject the spent shell, to chamber a fresh one from a magazine and to cock the mainspring, placing the gun in position for another shot with nothing more needing to be done than to provide another pull on the trigger.
Shotgun
A shotgun is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug. Shotguns come in a wide variety of sizes, ranging from 5.5 mm (.22 inch) bore up to 5 cm (2 inch) bore, and in a range of firearm operating mechanisms, including breech loading, single-barreled, double or combination gun, pump-action, bolt-, and lever-action, semi-automatic, and even fully-automatic variants.
Sight
A sight is an optical device used to assist aim by guiding the eye and aligning it with a weapon or other item to be pointed. Various forms of sights exist, such as iron sights, laser sights, reflex sights, peep sights, and telescopic sights.
Single Action (SA)
An action type, typical on handguns, where the hammer must be cocked manually prior to each shot (if it be a revolver) or prior to the first shot with an already loaded chamber and de-cocked hammer (if it be a semi-automatic). 
Single Set Trigger
A single trigger, operating at a normal 4 - 6lb pull, which when pushed forward converts to a hair trigger.
Single Shot
A firearm into which each shot must be manually loaded before it can be fired.
Skeet
Competitive shotgun shooting at 'clay pigeons' thrown from two different locations.
Sling (Sling Swivels)
Special metal posts are screwed into the stock near the butt and on the fore-end. Between these a sling is attached using sling swivels to be used for carrying a rifle over the shoulder.
Slug
A single projectile designed to be fired from a shotgun.
Slug Gun
A shotgun specially designed for shooting slugs, usually equipped with rifle sights.
Soft Point
A bullet that has an exposed lead tip.
Stock
A stock, also known as a buttstock or shoulder stock, is a part of a rifle or other firearm, to which the barrel and firing mechanism are attached, that is held against one's shoulder when firing the gun. The stock provides a means for the shooter to firmly support the device and easily aim it.
Striker
A spring-driven firing pin.
