Here she is i know nothing about old uberti 1873. Date marks XX9

3 click hammer.

Opened her up and seen the trigger/bolt spring was broke at the tip. Doesnt affect function. I have tons of replacements but the screw is in place so good my gunsmithing screwdrivers can't renove it.
Otherwise perfect bore perfect timing and chamber to bore alignment.

XX9 is 1973. Tapping on the head of the screw might loosen it enough.

Drop or two of liquid wrench or something, let is soak for a couple days. Then tap. If you can get a helper to lightly tap on the screw driver, as you turn...that could...help!

In addition to the good suggestions already posted, if you have a drill press with a vise just secure the frame upside down in the jaws (suitably padded). Insert the appropriate-size screwdriver bit into the chuck, then use the quill to provide downward force on the screw head. Rotating the chuck by hand is usually all that is needed to remove the most stubborn screws.

Good luck, and don't torque that screw very much upon reassembly.
