I have the cosmic single pin and as I've said in some previous posts it is THE brightest sight I've ever seen. I had that Cobra radiant with a light and even with the light on it was not as bright as the cosmic. Has anyone seen the new sights from g5 outdoors? Check 'em out at g5outdoors.com. They're made of magnesium and they look awesome. They seem kinda' pricey though. I guess that's the price you pay for exotic metals and such.....
