I've had Troys both standard and DOAs, I tried out diamondheads and now can't go back.
I'm not going to replace every sight, but I'm only buying diamond heads from now on. I love how the front sight indexes perfectly thru the rear sightsights. Fast if your a little sloppy. If you take your time it really takes any guess work out of getting your sight picture right.
