Useless or useful? - LaserMax CenterFire Gripsense Light & Laser

Making the M&P Shield is supposed to be small, adding this light makes it hard to find a holster. So buying this makes your pistol bigger, heavier, and unable to carry. After you pass these hurdles, it makes the pistol feel amazing. Grip tech is fancy and it can be disabled, different modes, and batteries included!! The battery life in the cold Northeastern during winter had me worried but it has performed time and time again. Still troublesome finding a holster for this buy I managed to find one (Pyntek). He's a one man show so it's an understandable long wait time. Overall the light/laser is amazing for the price they have on Optic Planet. Most lasers cost the same.
