What’s Included
- Smith & Wesson factory cardboard box with end label (SKU 180021)

- Three factory S&W steel single-stack magazines: two 8-round and one 7-round (mix of extended-base and flush-base floorplates)
The M&P 9 Shield shown here is the no-thumb-safety configuration, identified by S&W SKU 180021 on the factory box label. It retains the model’s internal safety suite, including a hinged trigger safety and internal striker block, and incorporates the sear-deactivation lever for disassembly without pulling the trigger.
Its stainless-steel slide and 3.1-inch stainless barrel are treated with S&W’s black Armornite finish. Rear slide serrations aid manipulation, while the polymer frame uses the familiar M&P texturing for a secure hold.
The fixed white 3-dot sight system pairs a ramped white-dot front with a drift-adjustable two-dot rear for straightforward aiming. Capacity is 8+1 with the included magazines, and the right side of the frame is factory-marked “CAUTION—CAPABLE OF FIRING WITH MAGAZINE REMOVED.”
This example includes two 8-round and one 7-round factory magazines, offering a choice of extended or flush-base floorplates. The stainless-steel internal chassis underscores the Shield’s robust construction, and the U.S. manufacture aligns with the model’s established reputation for reliability.
