Years back while in the service, a bunch of us would shoot skeet on days off. We were standing in a circle discussing our rotation and loading up. When I chambered a round in my Win 1200 pump, it fired stirring up the gravel in the circle. We were all surprised and they thought i had fired it. I knew I hadn't. I showed them the safety still on. I stepped out of the circle and pumped the action, only holing the pistol grip. It went off again.

When i took it down, I found the firing pin had broken in half and the safety would push it out the bolt face. Made a new one and never had any other issues.
The shotgun was new and had only been used 2 other days.

If I hadn't been pointing at the ground either time, somebody could have been hurt.
