WARNING:
Safety Selector: Proper use of the safety selector is crucial to the safe use of the firearm. The safety selector is located on the left side of the gun, just above the pistol grip. To ensure the firearm is on “SAFE” the pointer on the safety selector will be pointed at the insignia showing a bullet with a circle and a line through it. To disengage the safety selector to allow the gun to fire, rotate the safety selector lever to the insignia with a bullet without a line through it. This will allow the gun to fire.
NEVER take the firearm off “SAFE” until you are ready to shoot.
Above picture shows “SAFE”
