    R3emington 1858: hammer slipping from full cock...

    ...and firing without the trigger being pulled!

    Any ideas what would cause such a thing to happen?

    Scear

    From your other post Jim I would think that the previous owner has been tinkering with the matching surfaces of the scear and bent.

    I would get it to the gun doctor before you do anything else.

    Cheers

    If it's ancient I'd look for wear on the sear.

    If it's modern I'd look at the trigger return spring.

    Pull the hammer back and watch the trigger, you should see it dropping in to the two sear notches. If not the spring has gone.

    Hold the hammer back then push the trigger forwards. If it moves to latch then either the spring is nadged or there is something getting in the way.

    If it drops into a rounded out full cock sear then gets pushed out when you let the hammer down you should see the trigger move backwards.

    HI JIm

    I'm with RH on this one

    Check the trigger return spring - my Father had a modern Rem NMA & the spring rusted (the gun had been well cared for too !)

    Cheers

    Thanks, all.

    I find this REALLY scary! Guns are worse when they go off when you don't want them to then when they don't go off when you do want them to.

    Trigger slipping off full cock

    I'd absolutely agree about the state of the spring. If there's no pressure on the trigger, the hammer should fall into the half cock notch as it drops. That suggests the spring isn't bearing heavily enough on the trigger. Likewise, if the tip of the trigger has become worn (often by clipping half cock notch) instead of hard surface, you end up with a rounded edge will is easy to slip. I had somethng similar happen to my original Remington in Valencia at the European Zone Championships where the trigger went so light it wasn't controllable. On returning and rehardening the trigger and tweaking the trigger spring, I shot a 95 with it (10 points better than Spain) two weeks later...

    I took it to the gunsmith on Saturday and he did a lot of adjusting but didn't have to replace any parts. It works properly now: did in the shop, at least.

    I'll be making another range visit with it in a couple of weeks . Will
