Remmy Gunsmithing Question

[Fox Creek Kid]

I just bought one of the new Uberti '58 factory conversions and think it's a swell piece, however a problem has developed. I completely dismantled the gun to degrease. By the way, I determined that you have to remove the conversion ring (held by one screw) in order to give the hammer & hand sufficient room to lower to unscrew the hand from the hammer. Back to the matter at hand. The trigger pull is incredible light, like 1 - 2 lbs.  , but after adjusting the strain screw and a few times being cocked the hammer won't stay ay full cock.  I "unstrained" the strain screw & removed & then reinserted the mainspring, adjusted the strain screw and after a few times being cocked it happened again.  I figure that possibly the bevel on the sear is bad as the hammer spring is "captive". Another idea is that after adusting the strain screw that the hammer spring's length is incorrect. Ideas?

Overtightening the strain screw will arch the spring rearward and effectively shorten it at the base of the hammer, to the extent that it can slip past the roller, so your solution may be to replace the spring, or find a better setting for the strain screw, if that is the problem.

If your problem is the sear notch or something inside interfering with the trigger travel you will have to look there.

Is there overtravel of the hammer past the full cock notch?  There should be a bit of overtravel to allow the sear enough clearance to drop into the hammer's notch.  Another thing that can imitate that problem is an overly long or burred hand, which pushes the cylinder to lockup before the sear is clear to drop.

I fixed it. Well, me & a gunsmith friend with better tools.  The hand "ate itself" on the burred cylinder ratchet. After I stoned the burrs on the hand off the hand was too short as it was factory timed wrongly.    Incredibly, we switched springs on an old Pietta hand & it works great!  Cleaned up the sear notch as well. I think the gun was timed in a hurry at the factory.
