Detailed Features
Three interchangeable backstraps let you fit the grip to your hand size, a practical feature for shooters with smaller or larger hands who want a consistent firing grip without modifications. The striker-fired action has a consistent trigger pull without a manual external safety, which simplifies the manual of arms. The polymer frame keeps weight manageable at under 2 lbs unloaded. Steel white dot sights are functional out of the box; many shooters upgrade to aftermarket night sights over time.
Usage
The M&P40 covers duty use, home defense, and range work. The 4.25" barrel is full-size, which helps accuracy at distance compared to compact variants. At 28.80 oz, it is heavier than a 9mm of similar size, which is typical of .40 S&W guns. The 10+1 capacity serves defensive and range use; some states have magazine restrictions that affect this.

Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
The grip on it the angle that's just about perfect you just come up it's not too wide feels good.

Customers Say
AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
Owners of the M&P40 Gen 2 generally report solid reliability and a comfortable grip. The interchangeable backstraps come up often as a practical feature that makes the gun fit different hand sizes without adding bulk. Build quality and durability get consistent positive remarks from owners who use the pistol for duty or regular range work.
The .40 S&W caliber is a point of regular debate in owner discussions. Many appreciate the terminal performance relative to 9mm, while others note that .40 generates more recoil and muzzle rise, and that ammunition cost and availability favor 9mm. Factory white dot sights work for most shooters but a portion of owners upgrade to night sights early on.
Weight comes up as a mild negative for those considering carry. At 28.80 oz unloaded it is heavier than comparable 9mm polymer pistols. Magazine capacity of 10+1 is occasionally noted as lower than modern competitors. Overall, it is regarded as a reliable, proven platform for the .40 S&W caliber.
