Bastion custom slide cover plates for Glock add a unique custom look to any Glock pistol. Our slide cover plates fit all Glock models 17-39 including Generation 4 and are easy to install and remove. Our plates are machined from T6 aluminum, hard coat anodized and are extremely durable making it a perfect replacement for the stock plastic slide cover plate. All of the images are laser etched into the surface of the plates, so they will not rub off.
