I just got a new Armory Life magazine. In it, there is a review of the Hellcat Pro by Scott Conditt. On page 18 there is a photograph of the view through the Hex Wasp sight on this pistol. It shows about half the front post and like I have tried to explain about 4 times, the red dot is lying on top of the front sight.
To co-witness means being able to effectively use the Iron sights if the RD is dead. It doesn't mean a perfect view of the entire front sight. If you can level them off and match the daylight, it is co-witnessing.
