I am in the market for a new subcompact 9mm carry gun. I currently carry a Glock 26 but would like something with an additional safety. I shot the M&P with thumb safety and XD (Backstrap Safety) today side-by-side. I shot both equally well. It seems like the XD is an easier transition from the Glock but I really like the feel of the Smith. What are your thoughts with respect to the pros and cons of each gun and their respective safety systems?
