The lock disengages automatically if the trigger is depressed. We did not fire this handgun. As with all previously owned firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Our Assessment: While this pistol seems quite unconventional, even weird, everything makes sense once the design principle is laid out. How do you make the most compact, concealable, most reliable, most durable, and simplest repeating .45 ACP pistol? In the late 1970s, you track down engineer and inventor Philip Lichtman and you get the Semmerling LM-4. With only 33 parts, manual operation and a locked breech, it’s about as simple and reliable as a repeater gets. At about 5 1/4″x4″x1″x1/4″, it’s about as small as you’ll get a repeating .45 ACP. Constructed from S7 tool steel and with parts examined by x-ray multiple times during production, you won’t find many tougher guns. While extensive hand-fitting, attention to detail, and a refusal to cut corners likely ended up pricing the Semmerling LM-4 out of production, it certainly succeeded in fulfilling its goals. Fewer than 600 of these pistols were produced before the name, design and tooling were sold to American Derringer and Semmerling closed their doors. It is speculated, based on the strict requirements for durability, reliability and concealability, that the pistol was developed at the behest of some shadowy government agency, but they were also offered for retail sale and are now quite the hot collector item. This example is in great condition with minor handling wear, a bright bore and strong mechanics. It also comes with a “thin” kit, a panel and screws to cover components for use with the grip panels removed. This exceptionally well built and exceedingly rare pistol will make a great addition to any collection. Please see our photos and good luck!
