I'm not talking about disarming drills, or patterns of attack/defense in the classical sense. I'm talking about someone tries to mug you, you draw your concealed weapon, you get tacked to the ground, and now you are fighting for your life with a gun or knife in one hand, trying to keep it from being taken from you and regaining your feet and/or using the weapon effectively whilst so engaged? Likewise, you are confronted by an armed hoodlum, you tackle him to the ground, and now you are the one trying to avoid being shot or stabbed, and to take away the weapon? Just curious. I'm not sure I've seen such discussion or training before. What I have seen are what we in karate might call 'one step' drills. The bad guy does this, you do that. You step thusly, block as such, grasp, twist, stab, slash, etc. But what happens when it all goes south and you end up in a heap on the ground? The BJJ guys have many escapes and ways to avoid being taken down, etc. But it all changes when one hand is holding a weapon, edged or noisy, or your enemy is. Is there training out there for that?
