Abstract: The present disclosure provides a handgun magazine spring comprising a plurality of coils including a top coil, a bottom coil, and intermediate coils wherein the intermediate coils each include opposing curved segments and a straight segment and wherein transition segments extend between the curved segments of adjacent intermediate coils. The intermediate coils include small intermediate coils and large intermediate coils. The straight segments of the coils are parallel to each other. The transition segments between the intermediate coils, however, are oblique with other transition segments.

Abstract: A firearm includes a manual safety assembly. The manual safety assembly includes a first manual safety lever that is removably attachable to a second manual safety lever. Each of the manual safety levers includes a lever portion and a connection portion that extends transversely from the lever portion. A blocking lever extends from the connection portion of the first manual safety lever so that the blocking lever is substantially parallel to the first manual lever portion. The manual safety assembly is coupled to the firearm so that the manual safety assembly may be configured in an engaged position in which the blocking lever inhibits movement of a trigger bar of the firearm to prevent the firearm from firing. The manual safety assembly may be moved into a disengaged position that allows movement of the trigger bar.
