Apologies if this should be in off-topic. I found a Krav Maga studio in my area and am going to try to check it out this week. The guy seems legit and is registered with stateside Krav Maga organization. My wife and I both carry, but I know there are times when we can't or maybe we'll just get caught off-guard, so I don't want to get to the point where we rely completely on our firearms and forgo other defensive techniques. You can't take a firearm everywhere, but you can always carry your skills.
Having no previous martial arts training, does anyone have any tips? What sort of expectations should I have from a Krav Maga professional so I know I'm not going to be learning some off-the-wall, useless garbage?
