Paranoid over what?? I think you are WAAAY overthinking this....it's a bag....so what if it says 5.11 on it? Unwanted attention??
Here's the thing...there are people who OC....and more often than not, other people STILL don't see the gun...Really, I wouldn't worry about it. I think you give people too much credit to put together 5.11 = gun
Following your logic...why would someone WANT to mess with you knowing (or suspecting) you are armed??
