I remember one anime (Crystal something-or-other, I think) in which a man was shooting at some people hiding behind a table with what is clearly supposed to be a .44 Mag and being unable to hurt them through the table. (Maybe that flimsy-looking wooden table has a titanium plate on the bottom...) Shortly after that, one of the people behind the table shoots down a huge chandelier with one shot from a tiny pocket gun that might be a .380 at best. I still chuckle when I remember that scene.
Jormungand is no exception to this rule. I only watched a little of it before I was distracted by more interested things, but I remember there being quite a bit of that stuff. I found a couple things while skimming what I had seen before. In episode one, someone loads a magazine from the wrong end. In episode three, there is a machine gun that has bullets pointed toward the user. For some reason, I doubt there are many of them that work that way.
Ultimately you need to decide for yourself if the show bothers you. If what I have said makes you cringe, you are probably right to stay away. If nothing I have said about Jormungand turns you off, you may very well find that you enjoy it.
