Questions & Answers
Please describe where the on/off switch is and whether there is a momentary on feature. Expert Answer

The ArmaLaser TR28 Touch-Activated Laser Sight has a master on/off switch located on the underside of the laser. Once turned on, as soon as you grip the pistol the laser will activate. The laser uses a contact point located on the base of the trigger guard that will sense your hand and activate the laser. The laser has a steady and pulse mode that can be changed between the two modes using the provided allen key.

Will this work on S&W M&P 2.0 performance 10mm? If not, what is the correct model? Manufacturer Answer

This will not fit the S&W M&P 2.0 10mm. The ArmaLaser TR32 is designed to fit S&W M&P 2.0 of all sizes that have a picatinny rail.

Armalaser sight by Rodney, April 23, 2021
I bought this laser sight for my S&W 380 EZ. Mounting it was very simple and straightforward. It’s compact and easy to use. Just had to tweak the sight adjustment screws to get it sighted in. Seems to be well made and the battery is easy to change.
