First defense or backup defense coupled with what you are up against are important factors.
Many people see the firearm as the first and last line of defense and never train for defense without it.
My thoughts are, have tactics for self-defense were the firearm is the last resort (depending on the situation it may very well be the first line of defense).
Some of the best things anyone can do for self-defense training are to
- Learn avoidance
- Become skilled in empty hand defense (they have no weapons or they have edge or impact weapons)
- Depending on the chances of various types of crimes in your area then choose secondary weapons according to this fact might help. It might be a secondary pistol, kubaton or knife
Personally past using my brain and empty hand skills my primary defense is either a Kubaton or new edition Gunting (Lapu Lapu Corto) by Bram Frank then comes the pistol.
