Glocks do have a safety, but legally speaking, guns don’t actually need a safety. They usually have one since it makes things a lot safer for the guy buying it. In fact, I can’t think of a gun that doesn’t have some form of a safety, outside of some reproduction muskets and other black powder guns. But it’s not legally required.
IIRC, those discharge were because the default trigger was heavy, as in its mass not trigger pull, and, if you dropped it at a certain angle, the inertia of the trigger would pull the trigger. The fix was Sig doing a free upgrade to a lighter trigger that wouldn’t have a much mass.

The recent Sig P 320 chosen by the US Army has variants with no manual safety and doesn’t have the trigger safety.
It still has internal safeties but there have been issues with accidental discharges with the earlier productions.
