    Anyone know of a sure-fire method for finding the "zero" for the TLR-2s? I generally shoot at 8-10 yards, and I am having a very difficult time getting the shots in a tight group using the laser. I am assuming that wherever the shots land on the target, I need to adjust the laser so the windage and elevatio to the center of the bullet impact shot group. Is that correct or is there a better method?

    Never mind! Found what I was looking for on the Streamlight site and on Glock Talk. If there is another method to follow as just a general process to follow, I would glad to hear your thoughts! THANKS!

    if you know POA to POI at the distance you want the laser sighted in to then just adjust the laser to the sights, pretty easy to do as long as you keep in mind that the laser works opposite of the sights, i.e sights force a downward alignment while the laser projects up.

  4. Can you point me towards the answer you found on glocktalk?

    And the one on the streamlight site? Couldnt find it

    If you think about it, there's only two ways to collimate a laser designator...

    1) Sweet Spot: The laser is set to converge with the bullet at a distance predetermined by the shooter--the sweet spot. The laser’s point of aim (POA) will be offset more or less, inside or outside the selected sweet spot’s point of impact (POI). This is the only way to set up the laser/light combos, where the laser emitter is far from the gun’s bore axis.

    2) Offset: If the laser emitter sits close to the gun’s bore axis, it can be set up to run parallel to the bullet's path, out to practical shooting ranges. The offset--say it's a half inch--is a known value, and is ignored or compensated for by the shooter. This is how the LaserMax guide rod lasers are set up, since the laser emitter sits so close to the bore axis.

    Both approaches work, and are plenty accurate for self-defense. Neither is intended for precision sniping.
