I really really like trijicon hd sights. I personally feel that the vtac sight this thread is about was "made to sell". Huge fan of kyle lamb and have trained with him multiple times, and not trying to make a dig at all. It's just my opinion, for what you paid me for it.
*I can engage targets from 1 to 100 yards with my trijicons. I honest don't feel that I am likely to make hits beyond that, or even at 100, responsibly. Maybe in a warzone, yes. However, I am a civilian. The legal application is not 100 yards for a handgun. Not only that, but I am accountable for every bullet I launch. I do not honestly feel competent to launch bullets past 50 yards without missing, even under ideal square range situations. I feel these sights would offer the premise of a capability that I have no business pretending to have. Ymmv, and I am sure it does. This is just my take.
