Also known as: M&P40 M2.0 Subcompact, M&P .40 Subcompact 2.0, M&P40 SC M2.0

Overview

The Smith & Wesson M&P40 M2.0 Subcompact is a subcompact, polymer-framed, striker-fired semi-automatic pistol chambered in .40 S&W. Introduced in 2019 alongside the 9mm Subcompact variant, the M&P40 M2.0 Subcompact combines the stopping power of the .40 S&W cartridge with the smallest frame size in the M&P M2.0 family. The pistol features a 3.6-inch stainless steel barrel with Armornite corrosion-resistant finish, 6.6-inch overall length, and 10+1 round capacity from flush-fit magazines. It inherits all M2.0 generation improvements including the extended steel chassis within the polymer frame for enhanced rigidity, aggressive grip texture on all surfaces critical for managing the .40 S&W's snappier recoil impulse in a subcompact frame, a refined flat-face trigger with approximately 5.5-pound pull weight and tactile/audible reset, and four interchangeable palmswell inserts for customizable hand fit. At 25.9 ounces unloaded, the M&P40 M2.0 Subcompact is slightly heavier than the 9mm variant due to the thicker barrel and slide dimensions required for the .40 S&W chambering. The pistol features an integral Picatinny accessory rail, white dot front and white two-dot rear steel sights, and is compatible with full-size M&P40 15-round magazines for extended capacity.

Notes

The M&P40 M2.0 Subcompact ships with two 10-round flush-fit magazines. It is compatible with M&P40 M2.0 Compact 13-round and full-size 15-round magazines with grip protrusion. Available with or without an ambidextrous manual thumb safety. The .40 S&W chambering in the subcompact frame produces notably more felt recoil than the 9mm variant, which is partially offset by the slightly heavier slide assembly. The Subcompact shares its frame dimensions with the 9mm M&P9 M2.0 Subcompact. Velocity loss from the 3.6-inch barrel compared to a full-size barrel is approximately 30-50 fps depending on ammunition.

Background

The M&P40 M2.0 Subcompact represents the smallest .40 S&W offering in the M&P lineup, designed for users who want the proven stopping power of the .40 caliber in a deep concealment package. While the industry trend has shifted back toward 9mm for duty and carry use, the .40 S&W retains a loyal following among shooters who value the cartridge's energy advantage and those in jurisdictions or agencies that still mandate or prefer the .40 caliber.
