I agree with most posters here on the subject of the practicality of the laser in a pocket SD gun.
I bought the BG380 with the integrated Insight Laser about 2-1/2 yrs ago. I have had no problems with the gun except for the laser. The integrated laser unit was hard to turn on, kept losing it's on target zero, would go off many times while shooting, etc. I sent it in to S&W for a replacement. They sent me a Crimson Trace replacement unit.
I had removed the laser unit from the gun sometime ago and have been using the gun without it. I closed the holes in the dust cover with plastic hole plugs. I probably will not install the new laser unit. By leaving it out, I don't have to constantly check the hold down/ mounting screw to make sure it doesn't back out and catch the slide! I also found that in the instructions for the Crimson Trace Laser, S&W states, Remove the laser unit before cleaning the gun. This in itself is a pain!
