OP, Do you have tritium sights on your pistol? I just got a PVS-14 and realized that those night sights become giant glowing orbs that can obscure a head sized target at room distance. Aiming at my head in the mirror from 6 feet covered my head completely. Even with the gain all the way down they're still like three little suns floating around in front of you.
I have an M9A3 so no red dot and can't say if a red dot would sit high enough to not be obscured, but those glowing dots would probably still be a distraction. I have a X300V which works great but no laser so I'm glad I found this thread, now I'm going to look into that Streamlight VIR-II unless Surefire makes a similar unit based on the X300 body. Lining up sights or looking through a little scope/window under NVGs sucks even under the best conditions, if you're going high tech AF with NV might as well get the full package and use an IR laser and light with it.
