M90 shotgun: Difference between revisions

The M90 shotgun is hefted like a rifle, with the user's dominant hand holding the primary pistol grip, and their off-hand supporting the weapon by holding onto the forend (or "pump"), which doubles as a stabilizing grip. As is typical of human firearms, in order to discharge the weapon, the trigger positioned at the top of the pistol grip must be depressed, usually with the user's index finger (if human). If the weapon is loaded with standard ammunition, the weapon's firing will take the form of a spray of pellets, referred to as "buckshot", which are quite powerful at close range but lose damage efficiency as the spray disperses and loses energy. The firing of the weapon produces a fiery muzzle flash as burning propellant gasses leave the barrel.<ref name="HCEG"/><ref name="H2G"/><ref name="H2AG"/>

Once the chambered round is fired, to do so again, the forend of the weapon is slid back across the weapon’s underside in the direction of the stock, retracting the bolt and removing the spent shell from the firing chamber. When the forend is fully retracted, the spent shell will have been ejected, and the way will have been cleared for the elevator to position a new round for the bolt to carry into the chamber when the slide is once again pushed forward in the direction of the muzzle. Once the weapon’s magazine is expended, new rounds must be inserted one at a time into the receiver to continue firing. It is possible at any time to top up the magazine with additional ammunition until it is full.<ref name="HCEG"/><ref name="H2G"/><ref name="H2AG"/>
