That is indeed what you have. Have the same in my Savage 110.

Looks like it might be rubbing on the stock on the left side.

Yes that is a SSS competition trigger.
Savage did install them on some models right out of the factory. (Prior to the release of the accu-trigger.) But it looks like yours is a round back, and I am guessing a Stevens 200. Either way that would not be factory.

It's a Savage Model 12 single shot, and I think the trigger was installed later. Thanks all!
