Janet, this gun does not have a manual thumb safety. The pistol does have a trigger safety, an internal safety, and a drop safety. The trigger safety and the trigger itself must be deliberately depressed at the same time. The trigger safety is designed to prevent the pistol from firing if it’s dropped or if the trigger is subjected to any pressure that isn’t a direct firing pull.

Janet, just the internal drop safety Ma'am. This M&P M2.0 Carry & Range Kit features the M&P M2.0 striker fire pistol with steel white dot sights, four interchangeable palmswell grip inserts and three magazines; polymer frame; stainless steel barrel and slide with Armornite finish; no thumb safety. Kit includes: Caldwell Tac Ops molded OWB retention holster; Caldwell Tac Ops double magazine holder; Maglula Uplula universal magazine loader and unloader.
