Colt CCO Sights..

I have this CCO and am considering putting night sights on this one. I think IIRC they are a henie sight. Can anyone confirm this?

When I think of Heinie sights, the "Straight 8" dot/inlay pattern comes to mind. Does the rear sight have a single dot below the notch? And can you show the back of the rear sight?

No rear view is like this. The front is a white dot.

Sorry, drawing a blank on the sights. :o But that is a nice looking gun. How does it shoot?

Well. I really like the CCO setup. I am debating on having custom work done to it. Turning it into a true custom or simply putting nights on it and carrying it that way...
