First of all, do yourself a favor and don't say hide. Hide is a word used by anti's to suggest that everybody concealing a firearm has ulterior motives that are criminal. Let's not assist them by engaging in the same abuse of the language.
Secondly, snatch and grab is entirely up to you. Don't want it to happen, be aware. A criminal will not even approach you unless you show him beyond a shadow of a doubt that you're asleep at the wheel as it were. Feel free to consult the existing thread about the myth of snatch and grab.
