I got my new LCP with Lasermax out to show my sister and the laser wouldn't come on. I'm hoping maybe the switch was on when I put it in the holster. Looked all over for a 1/3N battery and couldn't find one. Radio Shack had one, but I wasn't going to pay $14 for it. I ordered 3 from Amazon.com for a total of $16. Hopefully that will fix it.
