Sent you some PMs and an email.
As you know the front site was dead on arrival.
I just got off the phone with Trijicon.
Since I am not the original owner, if the problem was due to a defect they will replace the Tritium for $19.
If they determine the site suffered an impact or the vial broke due to abuse then they will not replace the Tritium vial at any cost.
So given this info, I would like to send them back to you for a refund since the front site was dead on arrival.
Please contact me.
