I think glow sights are gimmiks. The last thing I want in an emergency is sights that I have no time to "charge" and have varying degrees of brightness that I have to adjust for from barely usable 5o blinding and illuminating myself as a target.
Although the need for night sights at all is debateable, if thats what you want get the real night sights at least they are consistent and formulated to just the right brightness level to identify your sights in low light conditions
