I got it in a package deal and am not a laser kind of guy, so you're in luck.
It came on the gun and seemed to work well. POI was where the sights lined up. I never fired it. The guy I got it from said he fired his G19 about 400 times w/ the laser installed.
The date on the package says April 2005.
It seems to come w/ everything you need except the tool, but a small screwdriver or hex wrench works well.
$220 $210 shipped and insured (Priority) to the lower 48.
USPS money order please.
