Bought a 3rd Gen G19 a couple of weeks ago but haven't fired it yet. While inspecting the gun, I noticed that the rear sights appear to be just a tad off center to the right. I can also feel it by running my thumb down both sides of the sight. Does anyone else notice this with their gun? Again, its barely off, but it makes me wonder how accurate this gun will be. I'd hate to send this gun off for something so trivial.
