Being a firearm owner is serious and requires similar seriousness of mindset and thought.

Carrying a firearm, even more so.

Carrying some firearms that may be less tolerant of poor training and stupid behavior, another notch up.

Some people think a gun is a talisman and don't cultivate a sound mindset and trained performance. It is not possible to have an unintended discharge (ND, maybe AD) with a properly functioning Glock unless one deviates from sound gun handling by a staggering amount.
