Press release:
LaserLyte is thrilled to announce the expansion of its Side Mount Laser (SML) line to now offer a unit that fits nearly all Smith & Wesson J-frame revolvers including 637 and 642 models. The new and inventive SML is easily mounted underneath the rubber grip of the revolver and is the only laser system available that allows the customer to retain the factory grip and holster the firearm. The SML will also work with many popular aftermarket rubber grips such as Hogue or Pachmayr brands.
To install the SML simply choose one of two included base plates that fits the revolver, temporarily remove the grip and screw the unit into place. Sight in is simple with common X and Y adjustments. The SML’s activation switch is strategically placed at the back of the laser and is easily turned on by pressing the button on draw or when holstered.
First press of the button produces constant on mode, second press produces pulse mode and third press deactivates the laser. The SML also has a customer-requested auto-off feature that displays a unique flash after five minutes of operation and automatically turns the unit off after six minutes. Press the button at any time to reset this feature that prevents accidental activation and battery depletion. The unit is also easily moved from one Smith & Wesson J-frame revolver to another.
Not sure, but it does not look like the gun with the laser on it would fit in some of the holsters I have for a J-Frame. I would also be concerned about the laser catching on clothes, it does not appear to be smooth like the Crimson Trace product.
Unless there is somehting else not readily visible (extended battery life, brighter dot, easier activation) I think I'll pass.
Just my opinion YMMV.
