Yes, the thumb safety on the M&Ps is really lighter than it could or should be. However, you have to realize that the thumb safety is completely superfluous on the M&P. All it does is block trigger movement.

Rule #3: Keep your finger off the trigger until pointed in at the intended target.

Holster: Get a proper holster that covers the trigger.

Follow these two rules and there is no need for the thumb safety.

I suspect that even if you send it to S&W, it will come back exactly as it already is.
