I replaced the L shaped spring with .050" piano wire. That dropped the weight. I have also filed the factory spring, tapering toward the back end, then heating it until it was blue, to take the hardness down. That helped, too, if you can't find piano wire. Piano tuners will have it.
I also lightly stoned the engagement surfaces and lubed with molybdenum disulphide grease. The surfaces are case hardened, so you can't go crazy with the stoning. The hard surface is just that ...... on the surface of the metal.
However, even though lightened, the triggers still stay a bit "spongy" due to the slop in the trigger/axle/housing.
The best thing to do is replace the trigger. I have 3 Sharp Shooter Supply triggers on my early Savages, which are the same as the Stevens 200.
