I have been asked a number of times over the years what handgun round I prefer to carry & why. It’s not a simple, nor fast question to answer so shall make an attempt to do so here.
The rounds you will find by my side most of the time are some form of expanding 9mm hollow points. They are not +P’s or +P+’s, just your regular octane leaded type. Before I go on let’s get the definitions for mechanics of projectile wounding out there:
1. Penetration: The tissue through which the projectile passes, and which it disrupts or destroys.
2. Permanent Cavity: The volume of space once occupied by tissue that has been destroyed by the passage of a projectile. This is a function of penetration and the frontal area of the projectile. Quite simply, it is the hole left by the passage of a bullet.
3. Temporary Cavity: The expansion of the permanent cavity by stretching due to the transfer of kinetic energy during the projectiles passage.
4. Fragmentation: Projectile pieces of secondary fragment of bone which is impelled outward from the permanent cavity and may sever muscle tissue, blood vessels, etc. apart from the permanent cavity. 1, 2 Fragmentation is not necessarily present in every projectile wound. It may or may, or may not, occur and can be considered a secondary effect. 3
