So the front runners are Truglo, Ameriglo and Trijicon.. anyone know what kind of warranty the Ameiglo or the Truglo has?
FYI, I believe the front sight with the Ameriglo Hackthorns has a Trijicon insert, paired with an Ameriglo rear-sight...
At least my front sight says Trijicon on it.

You look at the picture there and see Trijicon written across the top.
Here is a good thread showing the sights
