The Smith & Wesson M&P 5.7 is a full-size semi-automatic pistol chambered in 5.7x28mm. It uses an internal hammer-fired, gas-operated locked-breech action and ships with two 22+1 magazines. The 5-inch barrel, 8.5-inch overall length, and 26.70 oz weight put it in standard full-size territory.

Detailed Features 

The TEMPO barrel system uses a gas-operated locked-breech design that prevents the barrel from unlocking until the bullet has cleared the gas port, which keeps cycling consistent. The flat-face trigger promotes repeatable finger placement. An integrated Picatinny-style rail runs under the frame for lights or lasers, and the optic-cut slide accepts common red dot footprints. Forward slide serrations give a secure purchase for press-checks or slide manipulations. 
 

Usage 

At the range the flat-face trigger and low 5.7x28mm recoil make fast follow-up shots manageable. The 22+1 capacity covers most defensive and competition needs without a magazine change. For carry, the full-size frame is less concealable than subcompacts but handles well for home defense or range use where size is less of a constraint.

Feedback on the M&P 5.7 Black tends to cluster around a few consistent points.

Accuracy and felt recoil get the most praise. The 5.7x28mm round is light-recoiling even from a full-size platform, which makes rapid strings easy to manage. Shooters report tight groups at typical range distances.

The 22+1 capacity is a practical advantage. For range sessions or defensive use, fewer reloads appeal to most users, and the two-magazine inclusion adds value at purchase.

Ergonomics hold up well across hand sizes. The textured grip and comfortable overall dimensions make extended sessions manageable, and most users adapt quickly from other M&P variants.

The 5.7x28mm caliber still drives debate. Low recoil and high velocity are consistently praised; stopping power relative to 9mm or .40 S&W remains a recurring question, particularly for self-defense applications. Ammunition cost and availability compared to common pistol calibers are the most-cited practical drawbacks.

Build quality impressions are positive across the board. Users describe the Armornite finish and overall fit as what you'd expect from a Smith & Wesson pistol.

Customization interest is steady. The optic cut and Picatinny rail mean this gun takes accessories without modifications, which matters to shooters who want to add a red dot or light.

The trigger feels great, capacity is generous, and recoil is virtually absent.
