Abstract: A device for loading cartridges into the chambers of a revolver has a plate against which the bases of the cartridges are placed, a set of detents arranged around the plate to hold rims on each of the cartridge bases, and a spring for urging the detents and rims against one another to hold the cartridges in place. The set of detents can be rotated so that they release the cartridges, and when this happens, the cartridges are pushed axially into the revolver chambers by the spring. A locking device can hold the cartridges and detents in engagement, and this locking can be released automatically as the cartridges are introduced into the chambers of the revolver.
