    Winchester 1400 trigger/sear issue

    I've got a Winchester 1400 in 12 gauge that I've had since new (1967). Between then and now, it has been used heavily... always cared for and maintained, but used heavily for skeet, hunting etc. After all these years of faithful, reliable service, it had a stoppage yesterday during the dove opener, and it was a show-stopper for that gun. I always take a backup gun to the field, so I went about my day.

    The failure is thus - the bolt sets the hammer ok, but when the trigger is pulled it does not disengage the sear to release the hammer. I took the trigger group out to inspect it. It is clean and free of debris, and everything pivots and moves as it should. There are no broken springs.

    I compared it to the trigger group of my similar 20 gauge, and it appears that when the trigger is pulled the "bump" on the back of the trigger does not touch or barely touches the bottom corner of the sear. I'm assuming that after all these years and countless thousands of rounds, I've worn out either the trigger, sear, or both. These parts are available and inexpensive, and I can take the trigger group apart and replace the parts.

    What I am asking for here is this - do any of you have experience with this particular shotgun, and if so have you seen this issue? Am I on the right track with my diagnosis, and/or is there anything else I need to look at or consider?

    Well.............. nevermind.

    Turns out, there was one little #8 bb smashed flat in the disconnect, keeping the trigger from tripping the sear.

    I'm back in business.

      I found a primer anvil to be the cause of problems in an AR fire control group once.

        Apparently, one of my reloads must have had a bad crimp and leaked some shot into the trigger group. Froze up the gun, right in the middle of the action on the dove opener.

        I had a spare gun in the truck, but on the walk back I was getting buzzed by doves left and right and could do nothing but point my finger at them.
