A concealable speed loader for firearms includes a flexible, one-piece
body having a flat open condition, a closed annular condition, two ends
and a given width. The body has grasping chambers for receiving
cartridges with a length substantially greater than the given width,
causing part of the length of the cartridges to protrude from the body in
both the open and the closed conditions. A locking latch latches the two
ends of the body in the closed condition for placement above a cylinder
of a firearm with the cartridges protruding into chambers of the
cylinder. The locking latch has a knob to be pulled for manually removing
the body and releasing the cartridges in turn as the cylinder rotates and
the cartridges drop fully into the chambers of the cylinder. A method for
loading a firearm is also provided.
