I had a Vortex Venom installed on my Glock 17. During a shooting session, a crack appreared on the lower left of the glass. It looked as if an object hit the glass although I did not hear the hit; it may have been that I was focused on shooting and with the hearing protection and recoil, I may have have not noticed the hit. It may have been an ejected case which would have been an unusual low trajectory but maybe the motion of the hands under recoil may have intercepted the case.
I emailed them about this and they said ship it in and they replaced it!
