REVIEW: The New Smith & Wesson M&P Shield Plus The micro-compact striker-fired pistol market just received its latest contender! Joining the ranks of Glock, SIG Sauer, and Springfield, the new Smith & Wesson M&P Shield Plus is the latest double-stack 9mm micro-compact pistol to put its name in the ring.

So is the M&P Shield Plus going to sink or swim in the waters of the micro-compact 9mm carry pistol arena? Let’s find out.
