Gold trigger does not have any special designation. Until you ask a gun dealer at the gun show anyway. No, really, in the booklet that Marlin sent me, they even have it in writing that gold triggers are used in many models and many years, that no special designation exists.
I used to like it on my 1982 336 30-30, but now with it all tricked out and camo stocks, I wich it didn't have it.
