I just got my new Truglow TFX sights and installed them tonight. I bought front and rear sight tools and installed both front and rears. I used calipers to make sure the rears were perfectly centered on the slide, but the front sight looked a bit crooked compared to the slide, so I took a measurement and sure enough, it was off a tiny bit side to side at the rear of the sight to the side of the slide. I loosened the screw and the sight was fully seated, so it had no play. I removed the sight and reseated it and it still looked a bit crooked so I put a straight edge along the sight, it was obviously off. The oval hole sure looks straight in the slide, so all I can assume is that the sight is off. When I eyeball above the rear sights and line the edges of the front sight up, the dot would be centered almost with the right hand rear dot. Has anybody else had this issue? I don't know how to correct it other than removing the rear and sending them back. I do have a second set since I ordered a set for my wife's G19 as well.
