What safety features are on the Glock 40 cal?
Glock pistols use an internal http://www./topic/safety-firearms mechanism with three components, with no external thumb activated safety switch as might be found on traditional-design pistols. Glock calls this the "http://www./topic/safe-action" system. All three safeties are disabled one after the other when the trigger is depressed. They are: http://www./topic/trigger-firearms Safety: An external http://www./topic/lever mechanism contained within the trigger that prevents the trigger from moving unless the lever is depressed. Striker Safety: A spring-loaded pin attached by an extension bar to the trigger assembly blocks the striker from striking the http://www./topic/percussion-cap of the http://www./topic/cartridge-firearms until the trigger is pulled. Drop Safety: The far end of the same extension bar locks the striker into place from the rear until the trigger is pulled.These features apply to all GLOCK pistols.
