It is assumed that a user selecting to carry a concealed handgun for self
defense will select the most effective, readily available ammunition.
Ammunition effectiveness for this study is defined by the One-Shot-Stop
Percentage.
One-Shot-Stop Percentage is a number highly written about and highly
discussed in gun magazines.
Sanow, Marshall, and Fuller are usually associated with this topic and Sanow
and Marshall have published two books on the topic (the second book with
Fuller). Marshall uses actual street data in determining One-Shot-Stop
Percentage. Fuller uses a statistically derived equation in determining the
Fuller Index which is an estimate of One-Shot-Stop Percentage.
One-Shot-Stop Percentage (Fuller Index) is a number estimating how many
assailants will be “stopped” when hit by a One-Shot-Stop Hit.
