Closed boltA semi or full-automatic firearm which is said to fire from a closed bolt is one where, when ready to fire, a round is in the chamber and the bolt and working parts are forward. When the trigger is pulled, the firing pin or striker fires the round; the action is cycled by the energy of the shot, sending the bolt to the rear, which extracts and ejects the empty cartridge case; and the bolt goes forward, feeding a fresh round from the magazine into the chamber, ready for the next shot.

Pistol gripOn a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical (and thus more ergonomic) angle, similar to the how one would hold a conventional pistol. In firearms, the pistol grip is located behind the trigger and generally held by the hand that operates the trigger. Rifles and shotguns without pistol grips are generally referred to as having "straight" or "upland" (shotguns only) style stocks.
Drum magazineA drum magazine is a type of high-capacity magazine for firearms. Cylindrical in shape (similar to a drum), drum magazines store rounds in a spiral around the center of the magazine, facing the direction of the barrel. Drum magazines are contrasted with more common box-type magazines, which have a lower capacity and store rounds flat. The capacity of drum magazines varies, but is generally between 50 and 100 rounds. In 1853, the first revolving drum magazine was patented by Charles N.
Trafic d'armesLe trafic d'armes consiste à approvisionner en armes et/ou en munitions une entité (groupe combattant, association criminelle, État) en violant les réglementations internationales ou nationales sur les ventes d'armes. Sa définition reste floue, nombre de ventes d'armes se faisant sur le « marché gris » de l'armement. Le marché international du trafic d'armes est évalué à de dollars par an. En 2004, on estimait à 500 millions le nombre d’armes légères en circulation dans le monde, armes qui ne font l'objet d'aucun traité international – dont plus de 100 millions en Afrique, soit une arme pour 12 personnes.
ArmurierUn armurier est un professionnel qui conçoit, fabrique, modifie, répare ou vend, à l'origine des armes défensives, les armures. Avec l'apparition des armes à feu, le terme s'étendit également aux armes offensives. Par extension, l'armurier désigne aussi celui qui réalise les armoiries. Les armes défensives apparaissent parallèlement aux armes offensives. Avec elles, le métier d'armurier apparaît de facto dès la protohistoire.
