A speedloader is a device used to reduce the time and effort needed to reload a firearm. Speedloaders come in a variety of forms for reloading revolvers, or the magazines used with other types of firearms such as rifles and shotguns. Generally, speedloaders are used for loading multiple chambers of a revolver simultaneously. Such speedloaders are used for revolvers having either swing-out cylinders or top-break cylinders. Revolvers having fixed cylinders must be unloaded and loaded one chamber at a time. Speedloaders of different designs are used for loading the fixed tubular magazines of shotguns and rifles. Other speedloader designs are used to load the magazines (fixed or detachable) of semi-automatic firearms. Revolver speedloaders Cylindrical reloaders The modern revolver circular speedloader holds a full cylinder complement of cartridges in a secure fashion, spaced in a circular configuration so as to allow the cartridges to drop simultaneously into the cylinder easily (although non-circular types such as half moon clips are very common as well). A mechanism is provided that allows the cartridges to be released from the speedloader when loaded, so that when it is removed, the cartridges remain in the cylinder. The most common type of speedloader uses a rotating latch. Another type slides the cartridges out an open side; and a third type has a latch that releases when pressed. Revolver speedloaders make the process of reloading an appropriately matched revolver much faster than reloading one round at a time (provided that ready-loaded speedloaders are available). Swing-out and top-break revolvers are designed to eject all cartridges with one movement, and speedloaders allow loading with but a single additional step. They also provide a convenient way to carry ammunition for a revolver. Speedloaders do not, however, allow revolvers to be reloaded as fast as semiautomatic handguns without considerably more practice. Prior to the introduction of speedloaders for revolvers, reloading of revolvers was always accomplished by manually loading each cartridge into each chamber from cartridge loops on a belt or bandolier, a cartridge pouch, or other cartridge holder, such as a pocket. In fact, hand-loading is still the most common way of loading a revolver, speedloaders being mostly restricted to competition shooters and those who feel that they need more firepower for their personal defense revolver, since although speedloaders are useful for carrying one or several reloads at ready, one must load the speedloaders themselves prior to using.
