Need help again ,,1875 locking bolt

[willy]

Just got a used 1875 Uberti outlaw revolver.
Half cock will not keep the bolt down clear from cylinder notches.
If I cock it reallllllllll slow it will catch and then pop back up as soon as I move the cylinder .
So I got a new bolt.
It works when the cylinder is not in the gun .
But the gun freezes up when I put the cylinder in .
My thoughts is
#1 take some material off the locking bolt where it engages the locking notch.
Or
#2 Take some material off the leg of the locking bolt?
How much and from where?
What to do?

I have no clue actually (I know, no help).  Before removing material from anything, take a hard look at the Hammer.  It does not, to me, sound like a Bolt problem.  I sounds more like a wear problem with the hammer notches and cam.

Coffinmaker might be right. The hammer cams on these Italian replicas are often made of soft material and can wear rapidly, causing problems. That's the first thing to check. That being fine, then take a look at the arms on the bolt. I had one break off recently and it acted screwy before it came off completely.

I think you are right about the hammer ,
Tried a new bolt ,,no go..
Switched hammer from my other 1875,,
Walla!

Rather than buy a new hammer, which may have a soft cam like the original, look into having a good gunsmith replace the cam and it will be good to go for many, many years of use. I learned about this from a 'smith who does replace them with hardened ones.

If you can't find a good gunsmith who does this type of work and need the number of one, I can pm it to you.

Good advice, the cam is typical culprit. Replacing them isn't a huge challenge. I have a stash, purchased from Dixie gunworks. To repair, I first lightly grind the existing cam to provide a flat surface. Then center punch (eyeball accuracy works for me). Then drill to match size of the cam, using a drill press. Tap in & go. Lots of DIY folks just replace the hammer...but that's not my style 😆 Personally, I'd rather have a slightly soft cam, because replacing them (or adding a replacement) is easier/less time (IMO) than fitting a new bolt.

Fixed it,,used a dremil amd re cut the notch to catch the trigger a hair sooner.
