All good information.  I lightened the trigger pull on my Infantry Sharps, M1876, and my Spencer.  I removed the trigger group with Spring and took the spring off of it and using a Dremmell Tool with a sanding wheel began taking metal off the length of the trigger spring.  I had a container of water on the bench, and dropped the spring into it every so often to keep it from over heating and losing its temper.  I would then dry it off and reinstall it to check the trigger pull.  Once it was where I wanted it, I applied cold blue to the spring and oiled it up real good and put the rifle back together.  I'd take it out to the range and see how the trigger worked as well as how much improved my accuracy was as well.      YMMV.

Listen!  Do you hear that?  The roar of Cannons and the screams of the dying.  Ahh!  Music to my ears.

I was fiddling with the springs in my Shiloh Business Rifle with DST's. I ended up shipping it to Shiloh for an upgrade with fly, missing on my Early Farmingdale lock. Lesson learned?  Lock work is best left to people that understand such things

I lucked out with all of my single trigger Shilohs. All came with very acceptable trigger pulls, especially the percussion models.

I was on the phone yesterday talking to Charlie Hahns to order some new tubes for my 1859 Sharps paper cutter.  If you don't know
Charlie belongs to the NSSA and has a business converting the breech block so they rifles do not jam up with fouling.  Anyway I asked
if he worked on locks to smooth and lighten the trigger pull.  He told me to try this trick to reduce trigger pull before I sent toe lock
to him because this might solve my problem.  I now have an imprint of my palm on my fore head from smacking myself as in why
didn't I think of that !
    He told me some mainsprings have a ramp that the screw bears against that you can adjust in or out to adjust spring pressure on
the sear.  If mine didn't try putting brass shim between screw and spring until I got the tension I wanted on the sear.  Bingo so simple
in 15 min. I had reduced the trigger pull to my liking. 
    Now no grinding on the spring !  So simple even a caveman like me could do it  Grin

Hi Charlie

If you or Tom could POSSIBLY take or DRAW a picture of what's going on, that would be a huge help to me.  I read the whole 1886 trigger deal and mine is good, but my Cavalry Sharps trigger is HEAVY.  Most of the pictures I've found are small but most show a double set trigger anyway.

Howdy again

My 1911 smith smoothed out the trigger on the sharps and it's well under 5 pounds now.  I should probably weigh it some time.  It is SOOOOOOO much better now.  All that he did is smooth all of the bearing surfaces.
