SoCal Gunsmith for 90 year old gun

[CalifEd]

I would prefer a Gunsmith with experience with old S&W's SA's
This is a S&W Single Action .22 top break from 1910 that needs some attention.
It is too dangerous to fire.
It will cock, but sneeze and the hammer drops (aka the Baldwin feature).
I would like to get it back in a safe condition.

I am in South OC but will travel for a good gunsmith.

Is this a model 1 without a triggerguard?
If so, those are civil war era guns.
If it has a triggerguard, it's probably double action.

It is an 1891 2nd model top break Single Shot .22
DOB was around 1913.

Oh, that's a single shot.

You had originally called it a single action which would denote a revolver since revolvers are either single action or double action.
Then I was confused because I didn't know of any single action top-break 22 smith and wesson revolvers because the model 1 was a bottom break and smith didn't really make much if anything in 22 top break revolvers.

Single shots have very simple hammer/trigger arrangements.
Someone has either mucked with the fire control parts to make the trigger light/short or the parts have worn.
The fix is to detail strip the gun, clean it well and then increase the hammer/trigger engagement.

OOPS, My bad.
Was working on another SA issue this weekend.
That and my brain was not functioning this morning.

The problem is a dangerous push off.
I would hope that nobody was foolish enough to try and lighten the pull to that extent. Literally, it only takes a slight bump of the thumb to get the hammer to drop.

I will attempt a detail strip/clean this weekend and see what if anything jumps out.

Still, a good gunsmith that is familiar with pre-war S&W's would be nice.
I have a few that may need some work.

So while you have it apart, look closely at the hammer/trigger and see if there is obvious signs of them being worked on after Smith and Wesson made them or maybe they are just worn.
It also could be crud keeping the hammer and trigger from properly interacting.

I don't specialize in Smith & Wessons, but a simple hammer/trigger re-fitting to get proper engagement on a single shot action is not something that really needs a specialist.
You most likely just need to deepen the sear cut on the hammer so that the trigger will engage it deeper.
Also look at the angle to see if the angle is 90 degrees to the hammer pivot axis.
If you want less ability to push off and additional trigger pull weight, you can under-cut that angle to make it so that pulling the trigger causes the hammer to cock back a little more.
If you just want more engagement and a smoother pull, keep the engagement angle 90 degrees to the hammer axis while you deepen the cut.

Take it to Armstrong Arms in Laguna Hills.
