Anyone have one of these? I bought a Sig STL-900 tactical laser/light for my gun. When I first put it on the laser dot was well outside of center and there was a single dot. When I adjusted the laser to the center point of aim, per the instructions which are somewhat vague, a second smaller laser dot appears in conjunction with the bright one? It sits below the main dot and to the left when I have the laser sighted with the main light and sights on the gun. However, if I adjust the main laser about 1/3 of the way from the center point of aim (either to the left or right of the main light and gun sights) the smaller dot disappears all together and only the main laser dot is visible. However, the laser is obviously not centered on target, or on center with the main light with both pointed at a wall. The smaller dot isn't a huge issue but is distracting none the less. Am I missing something due to how the laser is aligned on the outside edge of the light housing? Do I have a faulty device? Is it some sort of lensing refraction? If this isn't normal I want to get it replaced.
