Frequently Asked Questions

What is a magazine disconnect safety?

A magazine disconnect safety is a feature on some firearms that prevents the trigger from being pulled and the gun from firing if the magazine is removed. It essentially 'disconnects' the firing mechanism when the magazine isn't in place.

How does the magazine disconnect safety work on the FN Five-seveN?

On the FN Five-seveN, the trigger mechanism is disabled when the magazine is removed. Once a magazine is fully inserted, the firearm's trigger becomes functional, allowing it to be fired.

Why were magazine disconnect safeties originally developed?

These safeties were developed in the early 1900s to assist individuals transitioning from revolvers to newly introduced semi-automatic handguns, who might not have been familiar with the mechanics of removing a magazine.

Does the FN Five-seveN have a magazine disconnect safety?

Yes, the FN Five-seveN is shown to have a magazine disconnect safety. The video demonstrates that the trigger is inoperable without a magazine inserted, but becomes functional once the magazine is properly seated.
