Abstract
Abstract A safety device for the striking bolt of a hand firearm comprises a spring-loaded safety bolt which in the safety position engages a recess in the axially slidable striking bolt and has an extension engaged by a safety lever operable by a trigger controlled by a pivotally mounted striking hammer. The safety lever has thereon a projection for the purpose of slidably moving the safety bolt and simultaneously therewith rotating a catch lever into a position in which the striking hammer is released. A special release lever which engages a projection on a release disk is adapted to disengage a catch lever and is effective to slowly move the striking hammer during its return stroke into its released position in which the catch lever is locked in safety position.
