LaserLyte has introduced a new red laser sighting system for pistols called the Rear Sight Laser. The LaserLyte Rear Sight Laser, or RSL, mounts in the position of the rear sight on a handgun, rather than as a grip or guide rod solution marketed by other companies such as Crimson Trace and LaserMax.
LaserLyte claims that by having the laser mounted to the rear sight, the holster can be used in all of the gun’s normal Level I and Level II holsters. While I do not have the laser on hand to test this claim with my own holsters, I can see how it should work with most holsters. However, there are no standards on what a Level I or II holster is, so the claim is a bit nebulous.
The laser is activated by a switch on the rear of the sight system. One press of the switch turns the laser on in a “constant” mode. A second press pulses the laser. A third press turns the unit off. Run time is marketed as one hour in continuous mode, two hours in pulse mode.
