    One of my friends resently bought an MB81 over under and we took it out yesterday for a couple rounds of doubles. It shot the first pair fine the second pair first round shot fine and the second round i had to pull the trigger a couple of times befor it shot. From then on out though it would not fire the second shot. Has anyone else had this problem and if so how where you able to fix it.

    Thanks

    Do you mean a DB-81? Make sure the internal slide selector is pushed all the way over. Sometimes the gun will double if it's not all the way engaged properly, mine did that once. Hap

    Pop the trigger assy out and take a peek at the back of the trigger, where it rests on the frame. There may be a piece of debris back there preventing the trigger from rotating forwad far enough to allow the inertia block assy from slipping back beneath the second sear.

    Your description of pulling the trigger several times, does not indicate the inertia block is NOT moving back, but, just not getting under the sear. This can be a problem once in a while if the trigger has been "tuned-up" to remove some preplay. The tolerance for dirt is near zero then.

    I have had similiar problems with a Perazzi trigger. The "cure" for mine was to flush the entire assembly completely with a good carburator cleaner. After spraying it down real good, blow it dry with an air gun. Then, I sprayed the entire trigger assembly with "Break-Free" lubricant. I really gave the trigger a bath with the Break Free. I then used the air gun again to blow out all the remaining lubricant, leaving the trigger with a very thin coating of Break Free. The trigger worked flawlessly after that.....
