Charlie,
Well ......... I can't really recommend the wire trigger/bolt springs. It's personal, but I just don't like the feel and I do think the wire springs contribute to throw-by. I use the Pietta trigger/bolt springs as a light replacement spring for all the guns I do action work on. That's a lot of guns by the way.
I do carry a supply of Trigger/bolt springs in my possables box "just in case." In ten years, I've only had to replace stock Uberti, stock Colt and USFA springs. I have yet to replace a Pietta spring. However, I do recommend you carry a spare Trigger/Bolt spring around with you. Murphy's Law.
