The safety button is located on the top rear portion of the receiver (Fig. 2) and must be
manually moved to the desired position by the shooter.
To put the safety in the “on” (safe) position, the safety button must be moved
fully rearward into the safety detent. The button will now cover the red dot. The red
dot is a training aid used only to show the direction of the “ON” (SAFE) position and
should not be used as an indicator that the safety is “ON” or “OFF” (Fig. 2). Moving the
safety button forward toward the muzzle of the shotgun will put the safety in the “OFF”
(FIRE) position.
Remember, a firearm’s manual safety is a mechanical device which can never
replace safe firearm handling practices.
Never rely on any mechanical mechanism or safety device to prevent the
dangers of careless handling or pointing a firearm in an unsafe direction.

The action lock lever is located on the left side of the trigger housing just rearward of the
trigger guard.
The action lock lever allows the action to be unlocked and opened for inspection of the
chamber and action or unloading without pulling the trigger. The action may be opened
by depressing the lever and pulling the forearm rearward (Fig. 3).
NOTE: During firing, the action unlocks automatically after the hammer falls and
the action can be cycled without depressing the action lock lever.
