Of course if a guy has a knife or gun drawn, he can have my wallet...LOL.

But, there are more scenarios than that. I certainly don't advocate fighting a guy with a gun or a knife, but, you may not have a choice. Some gym experience may help you a bit. Certainly gym experience is not the real thing, not even close but, I feel it should be done anyway. I have personally had a fight where a knife was involved and have some of my students. Neither of us are LEO but, we had little choice but to fight due to circumstances. I also have several LEO students who have had scuffles with weapons. It is very valuable to grapple with them - there are lots of drills for it. Also, it will make your no-weapon grappling better by giving you a very different awareness of issues of control
