Actually, you can remove the thumb safety with no adverse affect on the gun. The thumb safety on the M&P is largely innocuous. The only thing it does is block the trigger bar from moving. If you have the gun in a holster that covers the trigger, the thumb safety adds no value.

If you just have to have a laser, the Crimson Trace is the only one on the market worth having.

Just for my own weird inquisitiveness, why do you want one?
