Do the dots look painted on or does it look like a glass cylinder pressed into the sight? Thats probably the easiest way to tell short of calling them.Are the dot size the same? How do you tell the difference in the two if the night sight is dead? terry
No you're thinking of Phosphorescent paint. With Tritium you don't have to "recharge" it with light. Tritium is a radioactive material that'll glow constant for 10-12 years before noticing some dimming.So do night sights have to be in light every so often to charge them? And how long do they stay charged without light? terry
