I had an odd occurrence with my Benelli M2 today at the range. After functioning fine for an hour, I pulled the trigger and no bang. I held steady for 30 seconds and then pulled the action open, ejecting a live round with no marking on the primer, so it wasn't hit with a firing pin. There was also another shell on the elevator ready to go in. When I pulled the trigger, I knew something mechanical happened, which I then determined to be the sound/feel of the next shell loading from the tube onto the elevator like it is supposed to when you pull the trigger. It's as if the hammer was already forward before I pulled the trigger.
I fired a few more rounds fine, then I had another strange thing happen. Mind you, I'm bench rested here doing slug shooting, and before even putting my finger near the trigger, I heard something happen. In the confusion on the range, I cannot remember now if it was the sound of the firing pin going forward, or the sound of the next shell ejecting from the tube to the elevator. But it spontaneously did one of the two actions (maybe both) associated with pulling the trigger.
Analyzing it on the spot, I concluded that the trigger/hammer sear must be slipping and the firing pin block did its job preventing the gun from firing. It then went on to work fine for a good 20 more rounds.
But now, at home, I took it apart. For one thing, the sear will not slip no matter what, with the trigger group in my hand. I can bang it, shake it, pull in the hammer, nothing. Also interesting is I do not see a firing pin safety block, at least not one that I can understand. In a pistol and some rifles, the trigger pull pushes a spring loaded safety block out of the way, but I don't see anything like that here.
Any ideas what's up?
