Just got some trijicon  tritium night sights. the rear sight has the standard 2 apatures that you can flip between. Ones a "day sight" w/ the smaller peep hole and the other has the bigger peep hole but w/ 2 tritium inserts on either side of the peep. The front sight has 4 notches (A1 if I rember right) and is made of 2 parts, the bottom part w/ the threads and notches and the top part w/ the sight blade and notches that can be rotated independently of the bottom part some that you can have the tritium faceing you. They came w/ a 12 year warenty on the crafstman ship but not the glo life. They cost me $120.

Who makes 'em?
Where'd ya get 'em?

Trijicon
I bought 'em at my local dealer (Jim's Firearms in Baton Rouge, LA). I paid a bit more than if I'd bought them on-line but I knew I was probably paying high when I bought them and I definatly don't mind helping to keep this dealer in buisness.
