LM-4 Semmerling Pistol
This video analyzes the Semmerling LM4, a .45 ACP backup pistol developed by Philip R. Lichtman in the 1970s. It highlights the pistol's unique manually-operated forward-cycling system, designed for compactness. The review notes its historical lack of significance but discusses its expensive build with high-quality tool steels. The current production by American Derringer is criticized for its finicky manual action, unreliable magazine retention, and potential for self-inflicted wounds due to the short slide. The LM4 is deemed obsolete today, with lighter and more reliable 9mm alternatives and other .45 ACP options available.
