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.

Abstract: The present invention teaches about a separable magazine follower situated into a magazine body. The magazine follower includes a magazine follower body and exchangeable magazine follower plate. The upper surface of the plate tooth can engage a slide stop lever tooth after the last round is fired from the magazine, and moves a slide stop lever in position that holds a slide in the rear position. The magazine follower plate can be exchanged by the new one after being depleted. The magazine follower plate is not permanently secured to the magazine follower body, but it is nested into the magazine follower body and secured via a magazine spring. The magazine follower plate is formed from material of lower hardness than the material used for slide stop lever tooth in order to prevent its excessive wearing.
