A revolutionary feature was the use of a lever that either cocked or decocked (dropped the hammer) safely. This is the first handgun to have this type device (located on the left side below the slide, just forward of the grip). The hammer on the Sauer 38H could be lowered for safe carry at any time. The cocking feature was necessary due to the shrouded hammer and the decocking mechanism was a safety feature. A hollow space on the trigger indicated if the concealed hammer was cocked; if completely exposed, the hammer was lowered. A small pin protruded at the rear of the slide as a loaded chamber indicator.
