trigger pull on 1876

[doketx]

Hi guys,

     Does anyone know how to adjust the trigger pull (make it lighter) on a Uberti 1876?  I'd hate to pay a gunsmith to do it, but I also don't want to screw the gun up.  For some reason the trigger pull has very recently become horrible.  Thanks for any help you can give me.

Well, the three ingredients are (1) mainspring tension, (2) trigger spring tension & (3) sear engagement smoothness of surfaces.

On my rifle I thinned the mainspring (1) a bit & polished it well.
Smoothed rough edges on the trigger spring (2) & gave it a slight bend to reduce tension.
Polished sear surfaces lightly with a very fine stone - must be careful to maintain all correct (original) angles.

I also reduced tension on my lever spring (by bending slightly) as it originally required nearly a death grip to allow the rifle to fire.

When complete, I measured exactly a 3# trigger pull. Perfect for me.

If you choose to do this work, proceed slowly & test all operational features of the trigger thoroughly before live firing.
I have no idea what a smith would charge for this, but in my case it was about 2 hours of my time.

Since the trigger pull was good and suddenly it is not, I would tend to think it may be a problem with the sear, and this is something that should be taken to a gunsmith unless you have experience.  Or, possibly something could be binding?

These are wise words. I'd be taking a very close look at the mechanism under magnification. Unless I could find a problem that I felt comfortable fixing, I'd take it to a gunsmith that I could trust. Something changed (broke)...

Thanks for all your help, guys.  Gunsmith it is.

lucky it was ok at the start,  mine was awful from new.....before you get to work grinding springs check adjustment of the strain screw under the mainspring

Read thru this thread, I had trouble with my mainspring and this is how I got it fixed. Now I have a very smooth action and nice trigger pull. I know it's not really relevant but maybe it will help.
