Cause of two shots with one trigger pull

What is the cause of two rounds of fired with one trigger pull on a performance super sport 12 gage

[cas]

Could be a couple things. Just poor primary sear engagement, poor secondary sear engagement.  Gunked up, bound up parts, worn parts (all of which would be the same as what I said first)

[remarkable]

The Performance Center Super Sport was sent to Briley for Briley Parts as well as force coning work, back boring, trigger and action polishing.   Without seeing the gun my hunch is the disconnector and possibly the trigger shoe is now out of spec.  Please reach out if you would like additional insights on how to test the disconnector.

lol    Disconnector was the term they use that I was grasping for but coming up empty, so reverted to secondary sear.  :)

had the same thing happen to my super sport, the trigger was too heavy. it was tuned by a supposedly good gunsmith, unfortunately as it seems he had no idea about clearances between the disconnector and the hammer. this would cause the shotgun to fire two shots if you released the trigger slowly after you fired the first shot

You sure it isn’t your finger slapping the trigger a second time during recoil? On the Benelli, if the hammer isn’t being retained by the trigger or disconnector sear, the hammer will beat the bolt carrier’s movement. So you end up with the hammer forward against the bolt carrier. 
 

I’d take the trigger pack out and manipulate the hammer with the trigger pulled to see if the disconnector is engaging several times. See if the hammer is slipping past the sear and dropping. See as you release the trigger that the hammer disconnects from the disconnector and engages the trigger sear. You should be able to see this and hear this occurring.
