Notice! The rear switch units have actuators with O-ring seals for each switch. They remain in place quite well but pressing the switch when the unit is off the light body can push them a little out of place. Keep an eye on them when changing the switch unit.

Switch operating modes

The switches are the same on each side and allow momentary or constant operation without a two-stage "on and click". Press and hold for momentary action - the light goes off when you release. For constant operation, use a short click.

To toggle between laser only, laser + light, and light only, press both switches at the same time.

Enabling and disabling the strobe is a fun little adventure. Here goes: with the light off, start clicking rapidly and count the clicks. On the tenth, leave the switch depressed and wait for the light to present your choice: strobe/constant or constant only. Wait for the light to turn off and release.

When the strobe is enabled, the momentary and constant lights work as before. Double-click for strobe. (The laser is not fun at parties and remains constant even in strobe mode.)

Installation

The rail clamp attaches/detaches quickly and safely. Use a coin and don't tighten beyond finger-tight. The package includes rail lug "keys" for Glock-style, Picatinny, Beretta 90two, S&W 99 and S&W TSW, and Sig P320.

Zeroing the Laser

By default, there is nothing special about zeroing a sight with two screws. However, pay special attention if either of the screws binds, or the laser moves diagonally. If this happens, back out the other screw to allow the laser unit to move normally. The Allen key is only 0.05" so don't force it!
