I owned that package Lasermate gun sight It was an awesome idea and a complete piece off $hit. When they first came out they were over a hundred then quickly dropped. The main problem was the mount is made of plastic, a cheap plastic. I think if they used a better quality plastic or metal it would be perfect. I used it on my USP TACTICAL. It fell apart very quickly and eventually just stopped working. All the company has to do is make it of a better plastic and improve the mount and I think they would have a winner. I am talking within 200 rounds during IDPA.
