In answer to the questions from Stephen Boyd and gravelbelly, I need to elaborate on my comment on WARSKYLL about the Black Belt article dealing with pistol disarming.
I can't find any information online (I even tried a google search, and believe it or not I'm the first thing that comes up! :-O), so I highly recommend getting the issue itself. (It's the June issue.) Or, if either of you can't find one or for whatever reason, drop me a comment, we'll get into email contact, and I'll try to scan a PDF and send it to you.
The basic gist of it is not attacking straight on (no duh), not using the time-consuming zig-zag attack, and instead attacking in a crescent/half-moon shape (as seen from an overhead perspective).
Let me know guys, okay?
