John is man of action. He's seemingly always prepared. And, of course, he always wins the day. Let's be honest, he has the best plot armor around. With his name in the franchise title, how could he not? So, nothing really ever feels like a question as to whether John Wick will make it out of this sticky situation alive or not. We know he's going to. The fun of these films is finding out how he manages to survive — you know, by killing a couple of assassins with a pencil.
In the first film, we see that John has no financial worries. His days as an assassin were very lucrative. He owns a nice home and a beautiful vintage hot rod, and he has a stash of gold to boot. His firearms also can't come cheap. But there's one odd vacancy in his collection of battle gear: a bulletproof suit. In "Chapter 2," he's given a bulletproof suit from the armory at the Rome Continental. But he never owned one himself despite other high-profile assassins also having them on the job which seems odd.
The other question is how such a suit can withstand gunfire at point-blank range. John has taken a few bullets by the time "Parabellum" wraps up, some of which were Winston's three-feet-away shots pumped directly into the leading man's chest. Yet the suit seems undamaged, and John is no worse for wear when it comes to the shots fired at him. That's some real magic that even our own police force and military would be envious of.
