Arguments for Condition 3 carry (full magazine, nothing in the chamber):
1. Safer for children (more difficult for them to rack the slide and chamber a round).
2. Helps prevent negligent discharges by adding another task before firing
3. Helps prevent negligent discharges by reducing administrative handling during loading/unloading (you don’t have to chase the ejected round when unloading)
4. Lowers your chances of being shot by your own gun if a bad guy takes control of your weapon in a fight.
