But if you make it obvious, and you are at close range, now you have to pull the weapon from pocket despite resistance.
No I don't. If he goes for the hand I have on the pocket gun, all I have to do is release the gun while drawing my XDm 9mm with my strong hand, then shooting him full of holes.
MAIN POINT HERE:
BGs don't want a time-consuming fight, they want an easy mark. If you look like trouble, they're likely to wait for someone else.
The worst thing you can do is appear unaware, avoid eye contact, look unresisting.
If you look like food, you will be eaten.
