I was at a range in the parking lot chatting with a couple of guys. Then crackBANG! Someone launched a 9mm down the parking lot and over our heads. The owner of the 9 apologized and said his decocker failed. He was unable to replicate the accident. Was it an ND or did the decocker really fail? But since then I double check that the muzzle is in a safe direction before I hit the lever.
