Glock pistols are designed with three independent safety mechanisms to prevent accidental discharge. The system, designated "Safe Action" by Glock, consists of an external integrated trigger safety and two automatic internal safeties: a firing pin safety, and a drop safety.
Your Glock (my Glocks too) has three safeties, and you didn't even know. The important one is released by pulling the trigger. Looks like you need 30 days of training.
Looks like you need a sense of humor.
