I have seen pictures of Gen 1 Glock 17 for Pakistani Police with a serial # starting with GL made june 1989 with manuel safety I am sure there are others. I have also seen a Glock with a lock on the back of the slide to be unlocked with a handcuff key. Rare for sure but they are out there.Do any Glock models have safeties.....other than keep your finger off the trigger?
