My grandfather has an old cdl 700 that is older than me. The gun is atleast 35 years old if not older. He has never had the gun go off when taking the safety off. I tried getting my 700 to go off on its own but it wouldn't. I've seen the cnbc episode bashing the 700, but I've also seen the follow up where the truth came out. I believe what causes the guns to go off on their own are people messing with the trigger to give it a lighter pull. That's just my opinion.
