The magazine-indexing feed for a powder-actuated tool is for use with a disk-shaped cartridge magazine, actuated by the same trigger displacement as actuates the firing mechanism. A first link, pinned to the receiver, and a second link, pinned to an extension of the trigger, are pinned together, with a magazine engaging hook on the distal end of the first link. When the trigger is pulled, to fire the tool, the hook is displaced to engagement with the magazine. When the trigger is released the engaged hook is displaced, indexing the magazine.
