I am developing a game, and will be using guns in my game, I just am unsure of a few things. From what I understand, I need written permission to use the name of a gun due to the name being IP, but what about the gun's actual design? If I were to recreate a gun to give it the same 'Look', would infringing upon IP even be something to worry about?
Edit: I am not looking for a way to rip-off someone's IP, just for information so that I can get some guns designed, I am not full of ideas for what they should look like, so I'd like to base the design off of real guns.
