BudsGunShop.com - Glock factory Keracote??

Glock typically doesn't cerakote their frames, the colors are baked into the frame when they're being made, and they only come in Flat Dark Earth, "Tactical" Gray, Olive Drab Green, or straight up Black. You can almost guarantee that its either been cerakoted or duracoat by a distributor that Buds uses. It's unknown which distributor did the coating.
Fun fact, you can tell when a factory colored Glock is legit when the rails on the inside of the frame and serial number plate are NOT covered in what ever coating the distributor used. Also if you visit another gun shop and you see a butt load of boutique style of Glocks, as in pink, robins egg blue (turquoise), purple, red, etc. Then you can almost assume that it isn't factory.

Glock in GA will Cerakote the frames only. The slides are sent to another company like Lipseys for cerakoting. Then the slides are returned and reassembled by Glock in GA. Where these particular Navy style had their coating done, I do not know for sure. But the warranty is still intact.
