I purchased my brand new Glock 17 with TRUGLO night sights from a dealer sometime in July 2010. After 1k rounds or so, the actual front sight (not the mount, only the green) popped out a bit. It stills still inside the housing but it sticks out about 1-2cm. Second thing I just realized was the rear sights were mounted more toward the left side of the slide. I'm going back to the dealer tomorrow in hopes they will readjust the rear and repair the front under warranty. I wanted to see if anyone else encountered this problem and how you got it resolved? Are truglo sights under warranty? What can I do if they deny any service or to replace the sights?
