Tom Selleck loses temper gun-toting extra!

Tom Selleck has quite the temper!

The actor apparently flew off the handle when an extra on the set of his TV show Blue Bloods picked up a real gun and started pointing it at people!

The extra who was playing a cop but had never held a real gun was horrified when Tom, a lifelong gun enthusiast and board member of the National Rifle Association, spotted him and yelled, “Hey, YOU! What the HELL are you doing? That gun’s NOT a toy stop waving it around!”

“Look at you…your finger’s STILL ON THE TRIGGER!”

According to American tabloid the National Enquirer, the extra then squirmed, “Is the gun really loaded?”

Selleck replied, “No, it’s not loaded. But when you handle a gun it’s common sense to assume it IS loaded, and NOT point it at people!”
