Patented by Philip Lichtman in 1979, the Semmerling LM-4 is a unique sort of pistol. It’s a manually operated .45 ACP carry gun, intended to be the smallest magazine-fed gun of its caliber and also the best made. Retailing for a hefty $645 in 1979, the LM-4 was a low-production, handmade item marketed to a high class clientele.
