I purchased a new Glock 30 Gen 4 and the slide lock came from factory installed backwards. I love Glock. But was very disappointed that something like this would pass through quality. I called and informed them and they took a note of it but that s all. Didn t offer anything or a new slide lock. Was kind of disappointed with the customer service.
