Possible sure. Maybe not 100% likely though. The minute those teeth sink in and your nerves get damaged, the brain may not focus on the task at hand and focus more on the get loose and “flight” mode will kick in. This will limit your abilities to take care of the wolf. The damage inflicted could render your limb useless leading to another issue. Beat advice I could give is: give them the weak hand. K9’s tend to have fairly thin skulls in general. Use the strong hand to bash the skull. If you can daze him, you’re still in the game.

The first thing a wolf would do is knock you down then have his way with you.

Easy. You stick your hand down its throat grab its heart and rip it out. You could do the same by using the back door but that can get messy.

I think a wolf will decide how far your hand goes. And if it got any further than his molars, it will be because he swallowed it.

Once he got a hold of you by The throat or back of the neck or crotch you would be done.Wolves have enough musculature in their skull to give the jaw a crushing bite,they can crush moose bones.
If I had a choice of weapon(other than a firearm) to face down a wolf it would be a stout club.
