Owners of the M&P 40 Shield M2.0 consistently point to its slim profile as the main draw, making it a workable option for everyday carry without the bulk of a full-size pistol. The Armornite finish holds up well to holster wear, and the grip texture gets positive marks for retention under stress.

The thumb safety is a polarizing feature. Shooters who prefer a safety appreciate having it on a carry gun; others find it an unnecessary step in their draw stroke and train around it or wish it were absent. The trigger pull on the M2.0 generation is generally considered an improvement over earlier Shield variants, though it still splits opinions compared to other compact striker guns.

For .40 S&W fans who want a slim carry pistol, the Shield M2.0 fills a narrow niche well. Aftermarket support is solid, and the platform is familiar to anyone who has trained with M&P full-size guns. The main gripe from some owners is that .40 S&W ammunition cost and felt recoil in a compact frame make range sessions more expensive and fatiguing than 9mm alternatives.
