The complete DVD video (a bit dated but still interesting) can be be purchased online and provides far more detail and instruction (what you see here are excerpts only). This style of shooting has certainly worked for them (carry with no round in the chamber) and their routine is lightning fast. They don't even bother with a holster. Still, they tend to fire at further distances where the extra split second required to chamber a round is not critical. Also their focus is terrorist related vs. criminal and therefore legal constraints do not weight as heavily as they do in the US.
