The laser’s auto-off feature activates a warning pulse after five minutes of constant run time, and one minute later the laser turns off. Depressing the switch during the warning pulse resets the laser. Battery life is five hours of constant on, or 10 hours in pulse mode.
The unit is easily attached to the gun with the two provided extended pins. Allen wrenches are included for installation, changing the batteries, and adjusting windage and elevation. In addition to the Ruger LCP, the Side Mount Laser also fits Kel-Tec’s .32 ACP- and .380 ACP-chambered handguns using the included frame adapter. The laser also allows the use of most nylon pocket holsters. Price: $100.
