Yes for most glocks, although there are some glock models that do feature a manual safety.
Glocks have a half removeded striker once you rack the slide, and this gives a factory glock a trigger pull weight that is directly in between a removeded single-action trigger and an unremoveded 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 removeded 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.
