Questions & Answers
Does this come in left hard Expert Answer

Viridian does not offer a left hand specific option. They do now offer the instant on technology with an ambidextrous IWB holster, allowing you to turn on the laser with your draw. Here are links to the comparable lasers/holster combos from this page:

Helpful Positive Review Viridian Laser sight fo glock 42 by moresun, February 5, 2015
Laser was very easy to install, and was dead on at range! No adjustment needed. Holster had very stiff retention at first but loosened a little after several firm draws. You do have to remember to holster the weapon with laser on to work correctly.

Helpful Negative Review Not a perfect fit by BRITTANYMAN, Verified Owner, September 17, 2015
When installing this laser to my Glock 27 I found it did not have a tight fit on the trigger guard. It was loose and would move with a little pressure. I had to apply some teflon tape to the guard until the laser made a tight fit.

Most Recent Reviews Disappointed! by Douglas Elliott, Verified Owner, May 15, 2017
This product could not hold 'zero' for more than a moment. Pick up, put down, holster, present or fire; the laser point veered from impact point by several inches. I wasn't expecting Mil-Spec quality for the price, but 6 + inches between shots(or jus...
