In
the secured position the firing pin safety mechanically prevents
the firing pin from moving forward. A spring-loaded pin projects
into the firing pin cut-out and blocks it.
As
the trigger is pulled towards the rear, an extension on the
trigger bar pushes the firing pin safety up and opens the firing
pin channel.
This
safety can only be released by the trigger being pulled to the
rear.
This
situation offers maximum possible firing readiness combined with
maximum safety for the user.
