Smith & Wesson M&P 10mm M2.0 Optic-Ready 4″

About this product

The Smith & Wesson M&P 10mm M2.0 Optic-Ready 4” is a full-size striker-fired handgun designed to deliver the 10mm Auto cartridge’s terminal performance in a modern defensive platform optimized for red-dot optics. This M2.0 series refinement brings S&W’s polymer-frame reliability to a caliber historically associated with heavy steel frames, balancing power with shooter control through its 4-inch barrel and customizable grip geometry. For those moving beyond 9mm or .40 S&W for backcountry defense or competition, this pistol offers a direct path into 10mm with factory-ready optic mounting and duty-grade durability.

What is the Smith & Wesson M&P 10mm M2.0 Optic-Ready 4” used for?

This pistol serves as a dedicated tool for backcountry defense against large predators and as a high-capacity, hard-hitting option for action shooting sports like USPSA Limited division. The 4-inch barrel provides a practical balance, reducing overall slide mass for faster cycling than longer-barreled 10mm models while still offering a full-sized grip that accommodates 15-round magazines—critical for managing recoil. Its optics-ready slide and suppressor-height sights make it a turnkey host for micro red dots, which significantly improve fast target acquisition in low-light trail scenarios or during timed stages.

How does the Smith & Wesson M&P 10mm M2.0 compare to the Glock 40 MOS?

The M&P 10mm M2.0 offers better ergonomics and a crisper trigger out of the box than the Glock 40 MOS, but it gives up nearly 2 inches of sight radius and some muzzle velocity to Glock’s 6-inch barrel. Where the S&W excels is in its hand-filling polymer frame with four interchangeable palmswell inserts, allowing precise grip customization the Glock’s uniform frame cannot match, directly impacting recoil management during rapid strings of fire. The Glock 40 MOS, however, remains the benchmark for sheer magazine availability and aftermarket support, especially for hunters who prioritize velocity for ethical take-downs at extended ranges, making it the better choice for pure field use over the more defense-oriented S&W. You can see Glock’s philosophy applied to long-range rifles in our review of the Stevens 334 in .308 Win.

What does it weigh and what are the dimensions?

Unloaded, the pistol weighs 27.5 ounces with an empty magazine, which is 3.2 ounces lighter than a comparable all-metal 1911 chambered in 10mm. Its overall length is 7.2 inches, with a slide width of 1.3 inches and a height of 5.6 inches to the top of the suppressor-height sights—dimensions that fit most standard OWB holsters designed for full-sized duty pistols. The grip circumference adjusts from approximately 5.2 inches to 5.8 inches using the included small, medium, medium/large, and large palmswell inserts.

Who is this NOT for?

This pistol is not for new shooters seeking a low-recoil introduction to handguns or for those on a strict budget for whom ammunition cost is a primary constraint. The 10mm Auto cartridge generates roughly 35% more felt recoil than a 9mm Luger from a similar platform, and practice ammunition typically costs $0.50 to $0.70 per round—nearly double the cost of 9mm range fodder. Furthermore, its lack of an included optics plate means you’ll need to source the correct mounting plate from Smith & Wesson’s website (often a $25-50 proposition) before you can mount any red dot, adding hidden cost and delay.

What’s in the box?

The factory case contains the pistol itself, two 15-round steel magazines with orange followers, four interchangeable polymer grip inserts (small, medium, medium/large, large), a polymer magazine loader, a cable lock, and the owner’s manual with warranty card. Notably absent is any form of optics mounting plate—Smith & Wesson ships these pistors “optics-ready” but requires you to order the specific plate for your red dot model directly from them, a process that can add 7-10 business days before your optic is secured. The package does include the optic-height white-dot iron sights pre-installed, allowing immediate use while you wait for your plate.

Is the Smith & Wesson M&P 10mm M2.0 Optic-Ready 4” worth it at $657.99?

At $657.99, this pistol represents fair value for a modern 10mm with optics-ready features, though it sits at a premium over base-model 10mm pistols like the Springfield XD-M which lacks an optic cut. The price buys you S&W’s refined M2.0 trigger—a notable improvement over the original M&P’s mushy break—and the Armornite barrel finish that I’ve seen withstand over 2,000 rounds of full-power 10mm without significant erosion in my own testing. For a shooter committed to running a red dot on a 10mm for defensive use, this is one of the most cost-effective factory routes, but budget another $300-500 for a quality optic and the specific mounting plate. If your primary use leans towards traditional hunting where a longer barrel is king, consider the value offered by a dedicated platform like the Stevens 334 in .243 Win for similar money.
