Yes, not talking about the new push button safety on the receiver - that is a fairly recent addition - but the physical trigger block that is right behind the trigger. As the lever comes up, that part of it that forms the back of the trigger guard pushes up on a little tab which in turn raises the bar blocking the trigger so it can be pulled. It's a simple device to insure that the trigger cannot be pulled unless the lever is fully closed.

The 336 and 1894 have had that device since forever. So has the Model 94 Winchester as you mention.

Here is a picture of it. You can see the little tab that the lever pushes on and that little blocking bar just behind the trigger. That's actually one piece held in place by a pin and spring.

Hit the target, all else is twaddle!
