There are some Glock competition triggers out there which disable the built in safeties to make the trigger press smoother. If you know what you are doing, it is on you. If you are not sure how your trigger works, you should find out.
The guys at glockkraft.com made a video showing a quick and simple way to check that your drop safety is working correctly. Here, they check their trigger vs a competitor’s trigger and explain why their trigger is in fact better and safer.
