The Crimson Trace CTS-1400 Open Reflex Sight eliminates a great deal of the bulk of previous red-dot sight designs. Instead of an unwieldy casing holding the batteries and the sight adjustments as part of the optic itself, the CTS-1400 uses a slim “window” frame instead of a tube to hold the “glass.” This gives a heads-up-display-type view of the target and the surrounding area.
