I went through the laser craze for a while, had guide rod laser on a G-36, laser grips on a S&W 340, laser grips on my 1911 and a laser on my S&W 22A. They are all gone now. Having one on a target shooting or plinking weapon is fine and can be a lot of fun. My thought now is at an SD distance the laser is going to be a non issue, at 10 feet or so under the stress of whats going down, you won't even think about the laser. If you had the time to take cover and actually take aim it may be helpful.
Just my thoughts from having and shooting lasers on several makes and models.
But if CT were to come out with laser GRIPS (not a trigger guard laser) for the pup, I would probably try them, just for fun.
