I've been looking at these puppies for some time now, they look very good for target acquisition and speed. I've been thinking about putting a set of these on my new EDC a Springfield XD-9 subcompact. After seeing this review from The Box of Truth website http://www.theboxotruth.com/docs/pe1.htm
I'm maybe gonna send it to a gunsmith to be swapped out the front sight might be a realbear to remove myself. Other than that they are looking better all the time. Dead on out to over 50 feet is pretty darn impressive for a concealed carry pistol.
