This Smith & Wesson M&P40 is a solid choice for several types of shooters:
- Buy it if:
- You’re looking for a reliable, duty-sized pistol for home defense or concealed carry (if you can manage the size).
- You prefer the .40 S&W cartridge for its ballistic performance.
- You want a pistol with factory night sights already installed.
- You appreciate a good value in a used firearm from a reputable manufacturer.

Frequently Asked Questions about the Smith & Wesson M&P40
Is the .40 S&W cartridge still relevant for self-defense?
Yes, the .40 S&W remains a potent self-defense cartridge. While 9mm has seen a resurgence, the .40 S&W offers a good balance of capacity and energy, and many law enforcement agencies still issue or allow it. With modern ammunition, it’s a very capable round.
What condition is this used M&P40 in?
This particular Smith & Wesson M&P40 is in good used condition. It shows typical signs of use for a duty-style pistol but functions reliably. The night sights are present, and it includes the original factory case. We inspect all used firearms carefully before listing them.
Are magazines for the M&P40 readily available?
Yes, magazines for the Smith & Wesson M&P40 are widely available, both factory original and aftermarket options. Since the M&P series has been popular for a long time, finding spare magazines is generally not an issue.
What kind of recoil should I expect from a .40 S&W pistol?
The .40 S&W cartridge generally has more recoil than a 9mm but less than a .45 ACP. In a full-size polymer-framed pistol like the M&P40, the recoil is manageable for most shooters, especially with proper grip and stance. It’s a snappy recoil, but not punishing.
