The Vapor slide is designed with a combat-cut sight configuration. This optimizes the slide for use with a red dot optic, providing a clearer sight picture through the back of the optic with minimal obstruction. The slide is intended to have a red dot installed as the primary sighting system, with the iron sights providing a functional backup in the event of an optic failure. Because this slide is specifically designed to be used with a dot, we do not include – or even manufacture – a dedicated cover plate for the optic mount.
