When I carried the Bodyguard I trained without the laser. It was just too iffy to try and turn on the laser in a stressful situation with that button out front. The laser grips are a different animal but I still practice with the sights because batteries do die.The main reason I didn't go with the S&W Bodyguard with the laser is that I don't like relying on things that could fail at the worst times.
I think Kahr made a mistake by trying to jump into the budget 380 market. Then again they didn't ask my advise.
