Says you. Lloyd Irvin actually disarmed a home invader using some Chinese MA training. That's why he's able to have a CCW in Maryland, which is like winning the lottery....due to this incident. He talks about it here:
Knife disarming is the much more questionable, IMO, but I still train that too, as well as fighting w/blades. But gun disarming, certainly is legit. I didn't say it wasn't risky as hell. And yes, I have been in a firefight, although that really doesn't prove anything towards my argument about gun disarming.
If they haven't shot you yet, then they want something or may shoot you after they get it. It's up to your instincts to decide. But I'd rather have my chopsocky, gun disarming training then none at all. I train 5-6 days a week, 2-3 classes per day....doing something different with guns & knives are quite a welcomed changed, if anything.
