Sage13, you can easily change out the main spring for a lighter one. Aftermarket springs for Colt/Uberti etc. should fit, possibly needing the end trimmed a bit. This would make the biggest difference in feeling of the action. As long as it still pops primers, it will be fine. This will also lighten the trigger pull somewhat. A lighter trigger/bolt spring (also fairly universal fit) might also be good as well, as long as that doesn't make the trigger too light for you, and as long as the cylinder still locks up good at whatever speed you cock it.
