Very Reliable Springs
I have added Wolff springs to many Uberti revolvers in the past, both cartridge and cap & ball and they fit perfectly without modification and are very reliable. They give a much better reduced power hammer pull than stock factory springs. TIP: Add a 5mm x 5/32-in x 1mm stainless steel lock washer to the main spring screw as a spacer between the trigger guard and main spring. This extra 1mm of distance will reduce the hammer pull even more. I have read that back in the old days, they used leather banjo washers for this trick to reduce hammer pull.

Wolff Springs
This is my sixth set. I'm cowboy shooter and rely upon Wolff springs. They are lighter than factory springs but always give reliable ignition regardless of primer brand.

Great Spring
I put this on my Uberti Desperado .45 Colt. It fit perfect. It lightened up the hammer pull and mostly smoothed it out.
