Yes for most glocks, although there are some glock models that do feature a manual safety.
Glocks have a half cocked striker once you rack the slide, and this gives a factory glock a trigger pull weight that is directly in between a cocked single-action trigger and an uncocked double-action trigger.
Glock’s trigger safety is more secure than no safety although it is not as secure as a thumb safety, and the half cocked striker is easier to pull than a double-action trigger but is harder to pull than a single-action trigger.
Presumably this compromise was intentional and is one of the reasons why Glocks have become popular through their balance of reliability and ease of use - nowadays most striker fired pistols follow the same design principle.
From what others are saying, the trigger pull is always the same. I’m not familiar with the intricacies of Glocks specifically, but this seems to match with my experience as well.
