Approx a 1 1/2 years ago, I bought a new Glock 19. It just happened to have night sights. Just recently, I had the pistol in a completely dark room and noticed that I could not see the sights. I shined a flashlight on the sights for a while which did not help. Any body else have this problem with the factory night sights? I didn't buy this gun for its night sights, they just happened to be on the one and only 19 that the dealer had in stock. I do like the white outline rear, white dot front, as I most of my shooting is at a range under a roof.
