Fiber Optic sights on a carry/duty gun?

[NotDylan]

Does anyone run FO sights on their carry gun? I'm wanting to run a FO front only, what brands have proven to be the most durable? Also, how well do they work in low light, do they pick up any ambient light?

They break very easily.

Epoxy the inserts in there if you decide to run them, will cut down on breakage issues...usually the insert just falls out of the sight so the epoxy will be a huge help.

I use the HiViz (GL2007) overmolded model. Non overmolded models break very easily. My MP9 Pro sights broke already.
