So there's only 2 things I must preface.... first being that the only color available is black triggered with gold safety and second being there is an arrowhead laser engraved on the safety, which is the five logo for the company Empire collaborated with. I contacted Empire before I ordered to verify that these were legit and they confirmed that they are legit! https://tachuntfish.com/products/thf-trigger-shoe
