G31 Sight Issues

[hokie01]

I recently bought a new Glock 31 and have been experiencing trouble in sighting it in. I've had to move the rear sight all the way to the left and i'm still hitting to the right. I went ahead and drifted the sight till it stuck over the slide slighty and then trimmed the excess off with a knife. I'm now hitting on, but my question is what troubles will I experience when I decide to add a set of metal night sights? Could my problem be in the factory plastic sights? I noticed the front sight is at a slight angle and is not perfectly straight. Thanks for the help.
