It looks legit. Glock added a couple of metal rails to keep the switch sear from reaching the striker release. They better post shows the slide off and how the switch is installed and where the sear is you can see the risks and where they were dremmeled down easy peasy. Slight mod to the switch and take a harbor freight grade tool to the idiot rails and Bob’s your uncle.
