Sorry, I don't see the point.
I don't see the point of putting a coil hammer spring in the 1858 Remington.
Ruger has always used coil springs instead of flat leaf type springs, and they are very practical over the flat leaf type hand spring and split trigger bolt spring, I just do not see the need to replace the hammer spring with a Ruger style strut and coil spring.
I have never seen the leaf type of hammer spring break, in any single action revolver, with a Colt or Remington style action. As a matter of fact I have never seen a flat hammer spring break in a double action revolver either.
Changing over to coil springs always involves increasing the part count, because in addition to the spring a plunger is usually needed to impart the spring action to the part it is moving.
Look at how many more parts there are in a modern Ruger. Even without the transfer bar, a Ruger has more parts than a traditional Colt type action. Granted, the indestructibility of Ruger's hand and trigger/bolt spring make those parts superior to the analogous parts in a Colt. Trust me, I once had a trigger/bolt spring break at a CAS match and had to borrow a gun to finish the match. I always bring a back up set of Rugers in case something happens to one of my Colts. But I just don't see the point of putting a coil hammer spring and strut in the 1858 Remington.
