STL-900-WLL Updated – Replaces STL-900L

September 20th, 2011 Leave a comment Go to comments

Sig Sauer has a new version of its STL-900L laser/light combo. The new model number is STL-900-WLL (weapon laser light).

The STL-900-WLL has an updated design to make use easier.

The rear of the laser only has two buttons – both activate the light and are designed for ambidextrous use. The older model had four buttons on the rear – two on each side.

The left side of the STL-900-WLL has only two buttons where the prior model had three. The red button activates the laser and the black one switches it from solid to strobe.

Below are photos of the STL-900-WLL and it is available for purchase in our store. The specs identify the light as having a max output of 130 lumens and it has a 80 minute peak run time. Note that the box that the new laser ships in shows the older version of the light. The company must still be working on new packaging.

    I just mounted the STL-900-WLL on my HK USP 45 Compact and the ease of use and the accuracy of that little red dot is amazing, especially when it is zeroed with a laser boresight. It is light enough that it’s added weight to the front of the weapon is hardly noticable and I just love that little red dot.
