The Stevens rifle is basically the same as the Savage before the accutrigger. The actions, barrels, and parts are all interchangeable.
As far as a good trigger goes, you can spend $80-90 and get one from Sharp Shooter Supply. Fred and Lisa are really good people to deal with. I'm actually gonna call them tomorrow for the same thing. You can also get a Rifle Basix one from Cabelas or Midway.
If you dont want to spend alot of money, and will only be hunting with it, the factory 3 screw trigger is fully adjustable. You can get it down to about 2.5-3 lbs with little trouble. I have a copy of the proper directions to adjust it right from Savage and it is easy, but I dont think I can link it due to me being under 25 posts. If you want to post your email address I can email it to you though. It takes longer to take the stock off then it does to set the trigger.
Hope this helps,

Here is the directions. If it is unreadable try saving the pic to your pc and then print it out. If that dont workI can email it.
