I can't help but wonder - under what circumstance would I need glowing sights? Here's my reasoning: If it's so dark that the white-on-black sights don't provide adequate contrast & visibility, then I probably can't see my target well enough for a positive ID - unless I'm shooting from the dark and the target is lit, in which case, I'd be able to use the black outline of the sights to aim. Am I overlooking anything? Please school me ... Wanna kill these ads? We can help!
