I know of several companies who make triggers for the Savage Rifle
Canjar, Timney, SharpShooter, and Rifle Basix to name a few.
You will be hard pressed to find anyone who has tried anything but the SharpShooter. It was the first on the market, and nice enough to make people want to stick with it. I have yet to try one. My 10 FP trigger is sweet just the way I set it.
Good Luck!
