Thank you udsuna.

The gun for me is indeed more of a psychological tool then an actual weapon. Guns introduce an unrealable variable in such situations. I wrestle I know that the guy gots a big advantage that close up just from size alone. However, the break away I know can be done on people far bigger. Break away and draw gun(this would likely take sometraining). Normally by anyone with some knowledge you would be hit very soon after you broke out. However, if you draw the moment you get the chance(likely in the middle of your break away) then you can have the gun trained on them before the begin the hit on you. And for many the gun would at least induce a second hesitation(allowing you to back further up and further secure your safety). And if you keep backing up they may actually just decide to let you go(afterall you aren't telling them to stay still til the police come, you just want to leave). Course they may not want you to leave due to the fact that you could identify them. But some may rather risk that then death.

And yes guns can change hands. Which is why you have to be ready to expect such manuveurs(thought that still may not help).

As with anything you do need training with it. What I am trying to get accross is that MA alone won't protect you, a knife alone won't protect you, a gun alone wouldn't protect you, etc. But a mix of some of them and you increase your protection net.
