My argument is that we fight as we train. If a person goes to the range and loads and shoots their pistol without ever disengaing the safety........Because they never engaged the safety, the liklihood is fair to high they will forget to disengage the safety in a crunch.
However, if a person loads their pistol, chambers a round, engages the safety, and then holsters the weapon prior to drawing and shooting.......Every time they fire the weapon, then disengaging the safety becomes as natural as placing a finger on the trigger to fire the gun. If holster draws are not allowed at your range, load the pistol, chamber a round, engage the safety and table the weapon. Step away. Clear your head. Then step forward, pick up the weapon, bring it on target, disengage the safety and fire the pistol.
The answer is not one of safeties that disengage when a finger presses the trigger. The answer is one of training.
