Hopefully just an error. - TRYBE Defense Glock 43/43X Pistol Slide Version 2

I was impressed with the aesthetic and the build quality of the slide. As I was moving all the slide pieces from the standard slide to the Trybe slide I ran into some issues. The firing pin safety would not fit into the hole as it was milled by TRYBE. Thinking it was installer error, I took it to my departments firearms team, all certified Glock Armorers. They collectively tried to get the safety pin to work with no effect. The hole milled into the slide was too tight.
