It emphasizes that for most individuals, a consistent trigger pull and lack of manual safeties, as found in striker-fired 'Safe Action' pistols, offer the simplest and most reliable operation under stress. The instructors advise against DA/SA and manual safety pistols for beginners due to the added complexity and potential for error.

Frequently Asked Questions

What is the best handgun action type for self-defense?

For most individuals seeking a self-defense handgun, a striker-fired pistol with a 'Safe Action' trigger and no manual external safety is recommended. This design offers a consistent trigger pull and eliminates the complexity of manual safeties, which can be a liability under stress.

Why are manual safeties often discouraged for self-defense handguns?

Manual safeties add an extra step that can be forgotten or fumbled during a high-stress self-defense encounter. Accidental activation or failure to disengage them can render the firearm inoperable when it's needed most, making them a potential liability.

What is the difference between Single Action (SA) and Double Action (DA) triggers?

Single Action (SA) means the trigger only performs one action: releasing the hammer. Double Action (DA) means the trigger performs two actions: cocking the hammer and then releasing it. DA triggers are typically longer and heavier than SA triggers.

Are DA/SA handguns a good choice for beginners in self-defense?

DA/SA handguns are generally not recommended for beginners in self-defense. They feature two different trigger pulls (a long, heavy DA pull for the first shot and a lighter SA pull for subsequent shots), which can lead to inconsistent accuracy and a steeper learning curve under stress.
