Only the New York Times can be the source of so much ignorance.
NY Times' editorials about firearms are invariably the pits. The "dropped" Glock is designed to fire only with the trigger being engaged.
Safe Action System
The GLOCK Pistol's Safe Action trigger system offers you several very distinct benefits over conventional trigger systems. First, you can choose from several trigger pulls. Second, the trigger is the one and only operative control. Third, is the smooth and consistent pull you feel every time you squeeze the trigger. It makes training much easier because each and every single shot feels exactly the same. It also makes a firearm safe.
Three Safeties
GLOCK pistols have three independent and automatic safeties. As the trigger is pulled they sequentially disengage, and as the pistol fires and the trigger returns to its forward position, they reengage. The combination of the trigger safety, firing pin safety, and drop safety make the GLOCK the safest pistol on the market.
