Cylindrical reloaders black-powder cap-and-ball revolver replica. The cylinder has been removed from the frame. 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, handloading 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. Prior to the introduction of modern metallic cartridges (i.e. 1860–1879), certain models of older black powder cap and ball revolvers could be used with multiple replaceable cylinders functioning as "speedloaders". It was, however, generally easier to simply buy and carry a second revolver than to find a cylinder separately, and switching to another weapon is faster than swapping cylinders. As the reloading process for a cap and ball revolver was lengthy and time-consuming, carrying already-loaded cylinders with
percussion caps placed on cylinder nipples could offer a considerable improvement in reloading time, although historically, this was not typically done, and is more common among modern-day enthusiasts and exhibition shooters. When "spare cylinders" were carried, the weapons were usually
Remington revolvers, as their cylinders are easily removable and are held by a cylinder pin, unlike the early
Colt revolvers, which are held together by a wedge that goes through the cylinder pin. The first revolver speedloader patented was that of William H. Bell in 1879.
Moon clips and half moon clips ammunition
Moon clips and
half moon clips are special speedloaders for use with revolvers that chamber rimless cartridges, such as
9×19mm Parabellum or
.45 ACP. Double-action revolvers are designed to use rimmed cartridges, and the extractors are incapable of removing rimless cartridges. Because of this fact, a different method of extraction must be used. Moon clips are a full circle, and hold a full cylinder of cartridges, while half moon clips are semicircles that hold half a cylinder full of cartridges.
Speed strips Another variation of the speedloader for revolvers is the Speed Strip introduced by
Bianchi International. Intended as an alternative to loose rounds in a pocket or dump pouch, it holds six cartridges in a re-usable
Neoprene plastic strip. The strip operates by placing the cartridges one or two at a time into their respective chambers, and "breaking" the rounds off the strip into the chamber. ==Magazine loaders==
