To add to this:

    * Finger on the trigger. Very dangerous. Pulp Fiction showed the consequences
    * Using ball ammo

I actually dislike the pistols without manual safety. CCW people always say: but the Glock/P365/P320/VP9/... have an internal safety, a trigger safety and a drop safety.

But these safeties are not additive. If your trigger safety fails, the gun will go off. Same with the drop safety.

At least with a manual safety those are additional. It's not that because your car has an airbag that you stop wearing your seatbelt right?
