Hello, I'm new to the board what a great site and glad I found a sight with so much info on Single Shots. I have a Winchester 1885 recent production and if possibly I would like to get a set trigger for it. Who would be a good gunsmith or gunsmiths to talk to about this.
Thanks for your help
Mike

40 Rod 
It is a brand new Winchester USRAC made in japan by Miruko caliber is 45/70. It does have a metal tang if that matters.
Trigger is adjustable with one screw. No much of an adjustment. 
Thanks
Mike

The Dale53 trigger fix will do most of what you want.  And, you don't really need a lathe to do it.  I was between shops when I made several of these.  I used a vernier caliper, drill press, a hacksaw, and a file, and could make one of the screws in 5 minutes or so from a stock 7mm bolt.  They worked as well as the ones I make on my lathe.

Only caution I would have is make sure the trigger is broken in well before you do the Dale53 fix.  If the sear isn't slightly worn, it will wear and become unsafe quickly as you use it.   

On new rifles, I dry fire them about 100 times while putting extra pressure on the hammer with my thumb.  This will wear the sear edge enough to make the Dale53 fix stable.

Good Luck,
dave

Mike-The Dale53 fix is good and I am sure you could do it yourself.  But once you re-install the stock you have to remove the stock if you need to readjust the screw should the trigger wear in too much.   I would recommend the JB Innovations trigger screw fix (from Brownells) which does the same thing as Dale53 except does it by replacing the factory adjusting screw.   It can be adjusted anytime you need too.  In either case be carefull as both fixes work, but if set too light, both are prone to unintentional let off.   Best Regards Steve Witt

Gregg and Steve thank you, I've ordered the part from brownells and will see how that goes.
Thanks again,
Mike

Mike-Glad the JB suggestion is working for you.  Just be careful with it and be aware that as the trigger hammer and sears wear in some, the potential for inadvertent release also increases.  I use these myself on a couple Brownings, (same action as the new Winchesters) and they have worked well, but have had to make minor adjustments on a couple occassions.  As long as you stick to a light but reasonable pull weight there will be no problem..   Best Regards steve witt, waterloo, ia.
