I have a problem with my Savage 110. With the safety all the way to the rear, the bolt won't open. However, if the bolt is already cocked, it will fire.

If I slide the safety just a hair forward, it feels like there is supposed to be another position. However, at the position, the bolt cocks and the gun fires.

With the safety all the way forward, the bolt cocks and the gun fires.

In other words, the safety doesn't work!

Is this something I can fix myself, or should it go to a professional?

Where do I find the info on how it is supposed to be working?
