CT lasergrips; laser-aimers, shooting...
I owned a Taurus snub .357magnum Protector with a CT Lasergrip in 2004.
It worked well but you need to understand the limits & practical uses of laser aiming units.
Even Crimson Trace & the company instructors-cadre advise using the lasers to aid in marksmanship not replace it.
Green laser systems are better than the older red models but do not last as long.
Be aware of the training standards with laser-aimers or white lights & be ready to quickly adapt to NOT having them in a critical incident.
