So you can shoot in the dark? Impress me and prove it. If you can't see your target at 5 feet away, night sights ain't gonna help. Funny how you make assumptions, just like Jimmy thinking he's right about everything.
I'm not sure what you're saying exactly but night sights make a huge difference in low light.
Whether you're shooting from the 5 or the 50, your hit percentage will improve.
Of course "nights sights" is not exclusive to tritium these days since an RMS or some quality fiber optics can yield the same results. But I am a huge fan of tritium.
