Is 5.7Mm A Reliable Self-Defense Caliber?

The debate on the effectiveness of the 5.7 round as a self-defense caliber has been ongoing among firearm enthusiasts and experts for quite some time. The 5.7x28mm round was specifically designed for military use, primarily in the FN P90, as a replacement for the standard 9mm round.
