I never could get into that. I tried.
In this scenario, they grey man with the broken down rifle in the bag does sound like the best of both worlds, if you can pull it off. Which only OP could say for sure as it is an area he goes through regularly.
Another thought, do you have any contacts there in the "ghetto"? Could you get some? Diplomacy can work just as well as Arms if leveraged correctly. Not to mention saving a ton of time trying to get the right foundation to go with your skin.
