Yesterday I was admiring my 1980,336,30-30 and noticed that before the lever is in the fully "closed" position (depressing the little steel finger sticking down) I noticed it would still drop the hammer. I thought that the rifle wouldn't fire until that steel finger (for lack of a better term) was depressed as a safety feature. My other 336 will not fire until the lever is fully closed against the stock. Is there any wrong/dysfunctional with the 1980,336 ??
