Nitesighters
I bought some of their paint to make temporary night sights for an M&P I had to do a night qual with but didn't have night sights yet. It was quick to charge and brighter than any tritium sight on the line. I don't know if it worked all quals, as I had a chance to hit it a couple of seconds between strings while it was in the holster as "extra insurance." I put on 3 coats and 3 coats of clear nail polish after filling the dots with the stuff. Works pretty darn good for the money, checking it to see long it is useable after say, a 10 second dose of Surefire would be interesting. Haven't used any of there dots that they sent, but like the paint, they are BRIGHT compared to tritium sights or the old luminous paint.
