I know there is a lot of talk about this, including a thread from this week. I'm not debating if night sights are needed, I just want to know if these silly "rechargeable" glow paint sights are what they come with always or what. Mine is a USA AI code that came in a grey case (if that matters) The sight picture is great and I have no prob w-them, except for the glow gimmick. You can hit these babys w-an led light for a week and 15 minutes later they are back to ther "not glowing" mode. Are some just standard white? Are some Mepros?
