The fact that the gun came in larger variants fit for duty uses didn’t hurt, but what really made the Shield shine was concealability. Even with a single-stack magazine that boasted only a standard, non-extended capacity of 7+1 rounds, the Shield was incredibly popular for daily carry. Smith & Wesson claims to have manufactured and shipped more than 3 million of the guns, and that was back in 2019.
As a self-defense tool, the platform was simple, ergonomic, reliable, and affordable. But the single-stack magazine limited the gun in the face of the new wave of micro 9mm pistols like the Sig Sauer P365 and the Springfield Hellcat. Enter the M&P 9 Shield Plus with an enhanced 10+1 standard capacity, improved flat-faced trigger, and more grip texture all wrapped inside a gun that could be a near clone for the original Shield in size and function.
