Re: Handgun Sights
I had a similar experience at first, but then realized that I wasn't being consistent with which way I turned the little screws. I found the directions difficult to understand, but once I figured it out, and tried turning the thing like an eighth of a turn at a time, I managed to get it exactly right. One key thing is only turn one of them at a time. That is, get the horizontal/windage set correctly first, then worry about elevation/height. Or vice-versa. Whatever you do, don't overtighten, 'cause the little screw will come loose inside the unit and you'll never be able to get it out again.
What they say is in terms of moving the laser up and down or side to side, but not what effect that's going to have on the point of aim. But I figured that what's really going on is that the elevation screw is pushing the back end of the laser down when you screw it into the unit, so the point of impact is going up when you do that. It's the opposite of a conventional adjustable iron sight, if I recall correctly. And similarly, screwing the windage screw into the unit pushes the back end of the laser diode to the left, which means the point of aim is going to the right.
The main thing I recall is having been confused. So I've either got it right here or backwards. You'll need to experiment to be sure.
If you get to the point where nothing seems to be working, sometimes you have to back both screws out and start over. Seems the pressure from one will affect the other, if they're both in a good bit.
Here's their instructions, quoted verbatim:
Lasergrips are pre-sighted at the factory for 50ft. Many times no further adjustments are required. Lasergrips are fully adjustable for windage and elevation if further adjustments are desired. A good starting point is to align the laser with your fixed sights.
A two-screw alignment system is used to adjust for windage and elevation. The adjustment screws are located just behind the laser aperture. Place the included allen wrenches into the adjustment screws. To move the laser to the right, turn the windage screw clockwise. To move the laser up, turn the elevation screw clockwise.
DO NOT overturn adjustment screws. A little adjustment goes a long way.
Rarely is more than one complete turn required.
Start by adjusting the beam to line up with your fixed sights at the desired distance Most people sight In their laser at between 20 and 50 feet However, because of the small amount of mechanical offset between the laser and the bore, the actual change in point-of-impact from these distances is very small.
Occasionally one of the laser adjustment screws may not adjust enough to line up with your sight picture, or will not move the laser at all This is usually caused by over adjustment of the screws. To fix, back out both the elevation, and windage adjustment screws until you have 1 or 2 threads protruding from the diode housing on each screw. (Do not remove adjustment screws totally out of the diode housing) Tap on diode housing with a blunt, soft object such as the plastic butt end of a screw driver to reset the diode back into place inside the housing. Now begin turning the adjustment screws back down into the housing a quarter turn at a time, alternating between adjustment screws, (i.e. 1/4 turn windage screw, 1/4 turn elevation screw, repeat until both are back inside the diode housing.
