Frequently Asked Questions

Do I really need a light on my handgun for self-defense?

According to firearms expert Ken Hackathorn, a light on your handgun is generally not a necessity for civilian self-defense. While it can aid in target engagement, it violates fundamental safety rules during the locate and identify phases. A handheld flashlight is recommended as a safer and more versatile tool for civilians.

What are the safety risks of using a weapon-mounted light?

Using a weapon-mounted light to locate or identify a target violates firearm safety rule #2 (never point a weapon at anything you don't wish to destroy). Under stress, this can lead to unsafe finger-on-trigger habits. Additionally, a weapon light can become a 'bullet magnet' if the target is shooting back.

Why is a handheld flashlight better than a weapon light for civilians?

A handheld flashlight offers greater versatility and safety for civilians. It allows you to search, locate, and identify threats without pointing your firearm unnecessarily, thus avoiding legal issues like brandishing and adhering to firearm safety rules. It's also useful for everyday tasks.

When might a weapon-mounted light be justifiable?

Ken Hackathorn suggests specific applications where a weapon-mounted light might be justifiable, such as for a bedside gun, a backcountry firearm in bear country, or for law enforcement officers who have specific duties and legal authority to hunt threats. However, even then, proper training and adherence to safety are crucial.

What lessons were learned about weapon lights historically?

Historically, particularly before the war on terror, special operations personnel learned that white lights on guns could make them targets, leading to them being shot. This experience drove a rapid transition to night vision technology, as white lights were deemed too risky in combat scenarios.
