Well, as long as we're talkin springs, I too didn't like Rugers either . . . till I owned one!! I had to admit that Bill did a darn good job of introducing coil action springs to the Colt type action! They definitely extend the life of the parts/revolver as well as increasing the reliability of it. My mentor Jim Martin is not a fan of the coil spring and plunger for the hand for the above mentioned reason but told me "only do that modification on competition guns, they don't care if they put " beauty rings" on them !!" So, I justified doing the mod most folks want (the coil and plunger hand spring conversion) as long as it performs like the flat spring it is replacing. I did so (with a larger diameter. spring and plunger). That would keep Mr.Martin happy (it still behaved like a Colt) and customers would get the most reliable hand spring setup!! Win Win!!
With that taken care of, it became a mission for me to adapt the coil/torsion setup for the rest of the action and to all the platforms I work on Colt, Remington and 3 screw Rugers (yes, Rugers!)! It took quite some time to finally come up with the right formula for each platform but in the end, I think it offers even better performance than the original Ruger setup. These days I may do 1 or 2 flat spring setups a year with all the rest being converted to coils!
I would offer springs (bolt and hand maybe?) but there are some mods to the action parts for total conversion so that makes it a "no go". Converting a Remington to coils is rather " involved " so definitely Not user install friendly!!! But I will say, they are quite the beast when done! They are every bit as tough as the Ruger . . . just lighter!! In all, I think it's by far the best setup as it makes all of the platforms more a "Ruger that looks like a Colt/Remington or . . . just a better Ruger!!
So, for me, if it's not coils I'd go with modified flat springs before wire springs.
