Q: How do I install the RL-KA?

A: Once the stock rear sight is removed, the laser installs into the dovetail with a brass punch that comes with the laser. If you are unfamiliar with removing stock rear sights, we suggest consulting either Kahr Arms, your gun manual or taking the firearm to a certified gunsmith.

Q: How do I sight in the laser?

A: There are two screws located on the laser. One is on the top of the laser and is for elevation adjustment; the one on the right side of the laser is for windage adjustment.

Q: What do I do if I’m having trouble sighting the laser in?

A: Try the reset process; back the screws out for both the elevation and windage until there is a thread or two showing on each screw. Then let the laser sit turned off for at least one hour at room temperature then follow steps 1-6.

Laser Sight In:

  5. THIRD! Use both screws in ¼ turn increments to move dot above front sight. Making sure your final adjustment it clockwise.

Q: Why is the activation switch/button on the left hand side of the laser?

A: The activation switch/button is located on the left, back side of the RL-KA due to design and size. Also, research findings have shown that the majority would prefer the button to be on the left hand side so they may use their free hand to activate the laser.

Q: Why is it when I push the button the laser does not turn on? I have to push it twice?

A: The unit you have is now equipped with the new night sight. The first push of the button is the night sight (The LED glows green under the white sight notch creating a rear night sight). Second press of the button is constant (which you can program to pulse by holding the button down for 6 seconds) and the last press of the button turns the unit off. There is no longer an indicator light in the back.
