EC Defense is proud to introducing the MK-3 slide. This is where the fun started for us so no space was left open to interpretation on this model. Every angle, pocket, and serration was designed with maximum traction, reliability, and cooling in mind. If you look closely at the muzzel you will also see a decorative yet functional lightening pocket for added detail and a further example of our passion for machining finesse. Thought this is only EC Defense's midgrade offering, this slide competes for attention as EC Defense possible favorite.
