Query: A good overview of the Glock.

This DVD gives a good overview of what makes the Glock stand out from other handguns. It covers concealed carry holsters (If only this would apply to Australia), draw techniques and dry fire practice. With lots of good demonstrations this give a great introduction to the Glock series of handguns and what makes it stand out from the rest.
