The stainless steel construction of the barrel and slide maintains structural integrity while keeping the overall mass optimized for extended carry and use. You’ll find the weight distribution particularly advantageous during long training sessions or duty carry, minimizing operator fatigue without compromising performance.
Barrel Length
Standard configurations of S&W’s M&P 40 feature a precision-machined 4.25-inch barrel, though you’ll find this length varies across different models in the lineup.
The Semi-Auto Pistol M2.0 Compact offers a 4-inch barrel, while the SHIELD M variant comes with a shorter 3.1-inch configuration. Each barrel length is optimized for its intended use, whether it’s duty carry or concealed applications.
Material Made Out Of
Moving beyond barrel specifications, the structural components of the M&P 40 combine durability with precision engineering. You’ll find a stainless steel barrel and slide protected by a Melonite nitriding finish, ensuring corrosion resistance.
The lightweight polymer frame keeps the pistol at approximately 24 ounces while maintaining dimensional specifications of 1.2 inches wide, 5.5 inches tall, and 7.5 inches long.
Chambered In
Designed for optimal stopping power, the M&P 40 is chambered in .40 S&W caliber, featuring a 4.25-inch precision barrel in its full-size configuration.
You’ll find this chambering across multiple variants, including the M2.0 model w/ thumb safety and the Shield version. While the full-size maintains the standard 4.25-inch barrel length, the Shield variant utilizes a more compact 3.1-inch barrel for enhanced concealability.
Capacity
The M&P 40’s magazine capacity varies across its different configurations, with the full-size M2.0 model holding 15 rounds of .40 S&W ammunition in its flush-fit magazine.
The S&W M&P COMPACT features a reduced capacity, while the WESSON M&P SHIELD version of the MP offers 6 or 7-round magazines.
You’ll find aftermarket magazine extensions available through Smith & Wesson’s website for enhanced capacity options.
Trigger Pull
When examining the M&P 40’s trigger specifications, you’ll find a factory-set pull weight ranging from 6.5 to 7.5 pounds, delivering consistent, smooth operation throughout the stroke.
For enhanced performance, you can install an Apex Tactical trigger upgrade, reducing pull weight to 4-5 pounds. The short, crisp reset facilitates rapid follow-up shots, and the pistol’s available magazine disconnect feature maintains reliable safety standards.
Safety?
Safety features on the M&P 40 complement its trigger system through multiple integrated mechanisms. You’ll find an optional ambidextrous thumb safety and a removable magazine disconnect safety, providing flexibility in your preferred safety configuration.
The ambidextrous controls extend to both the slide release and reversible magazine release, ensuring you maintain positive control regardless of your dominant hand.
Action
Operating as a striker-fired semi-automatic pistol, the M&P40’s action delivers consistent trigger pulls while maintaining a 15-round capacity in .40 S&W.

You’ll find the stainless steel slide and barrel, treated with Melonite finish, work seamlessly together to ensure reliable cycling and operation.
Optic Ready?
The standard M&P40 doesn’t come with factory-installed optic mounting capabilities, requiring aftermarket modifications for red dot sight compatibility. You’ll need to either mill the slide or use third-party mounting plates to attach optics.
However, Smith & Wesson’s new M2.0 version offers a factory optics-ready solution, allowing direct mounting of red dot sights without additional modifications.
Review
You’ll find the M&P40’s proven reliability and ergonomic design deliver consistent performance, with the interchangeable backstraps and low bore axis contributing to enhanced control during rapid follow-up shots.

The smooth feeding of various ammunition types, combined with the ambidextrous controls and competitive price point, positions the M&P40 as a practical choice for both novice and experienced shooters seeking a duty-grade firearm.
