A friend of ours recently shared this.
“I pulled my 20 gauge semi-auto out to go deer hunting tonight. Action open, safety on….as always. Put a slug in the chamber and hit the button to close the action. The action slammed shut and BOOM! Again safety on and nothing near the trigger so actually two things failed….the safety and the firing pin was somehow in position to contact the casing when the action slammed shut.”
He got his truck bed with a solid hit. Remember, safety’s can fail. ALWAYS treat a gun as if it were loaded, and be sure to point the muzzle in a safe direction at ALL times.
