Fantastic laser at a great price - ArmaLaser Laser Sight for Sig Sauer

This laser is custom made to your gun model. It fits perfectly, is easy to install and is accurate. The laser is turned on when you grip the gun eliminating the awkward step of having to find a button when you pull the gun from yor holster. You can change the battery without having to remove the laser which means you do not have to re-zero after changing the battery. All of this for a fantastic price. Highly recommended.
