The triggers in post-mil (after 1960) 99's are atrocious. Not much that can be safely done with them other than to judiciously stone/polish the sear surfaces without messing up engagement geometry or amount of engagement. Not something the typical casual gun tinkerer should mess with IMO. By doing so you might, might, lower pull weight a pound or so, but it'll still be creepy mess. If that trigger is worked on to remove creep then you're dancing with potential slam fires. Like I said, the late Savage 99 trigger is not a masterpiece. My advice: leave it alone and learn to live with it like about a million other guys have.
