About this product
The Smith & Wesson M&P 5.7 5.7x28mm 5 in Optic-Ready Pistol is a full-size semi-auto built for shooters who want flat-shooting speed and low recoil in a reliable, optics-ready package. Chambered in 5.7x28mm, it uses the rotating Tempo® barrel system to tame muzzle rise and keep you on target fast. This model ships with two 10-round magazines in a state-compliant configuration.

Key Features
- Tempo® Rotating Barrel System — WHY IT MATTERS: This unique system delays barrel unlocking, reducing felt recoil and muzzle flip so you can make faster follow-up shots without fighting the gun.
- Optics-Ready Slide — WHY IT MATTERS: The slide is pre-milled for direct mounting of most micro red-dot sights (no plate needed for many popular models), so you can upgrade your sight picture in minutes.
- Flat-Face Aluminum Trigger — WHY IT MATTERS: A crisp, clean break with a short reset gives you more control and consistency, especially if you’re new to shooting or transitioning from a striker-fired gun.
- Integrated Picatinny-Style Rail — WHY IT MATTERS: Mount a light or laser directly to the polymer frame without adapters, making this pistol ready for low-light use or home defense.
- Two 10-Round Magazines Included — WHY IT MATTERS: You get two mags out of the box, so you can load one for the range and keep one for backup — and the 10-round capacity meets compliance in restricted states.
Who It's For
This pistol is a great fit for new gun owners who want a soft-shooting, easy-to-control handgun for the range or home defense. It also appeals to experienced shooters looking for a lightweight, high-capacity platform that runs clean and stays on target. Because 5.7x28mm ammunition is widely available and affordable, it’s a smart choice for anyone who wants to practice often without breaking the bank.
Pros & Cons
- Pros: Very low recoil for a full-size handgun; optics-ready out of the box; reliable feeding and ejection with the Tempo® barrel; lightweight polymer frame; two magazines included.
- Cons: The 10-round magazine capacity is lower than the standard 20-round option available in free states — if you live outside a restricted area, you may want to buy standard-capacity magazines separately.

FAQ
What optics fit the Smith & Wesson M&P 5.7 slide without an adapter plate?
The slide is milled to accept popular micro red-dot footprints, including Shield RMSc, JPoint, and similar patterns. For other optics, you may need an adapter plate — check with your optic manufacturer for specific fitment.
Is the Smith & Wesson M&P 5.7 California-compliant?
This model ships with two 10-round magazines and is designed for states with magazine capacity restrictions. However, California has its own handgun roster — please verify current roster status before ordering if you’re in CA.
Can I use +P ammunition in this pistol?
According to Smith & Wesson, the M&P 5.7 is designed for standard-pressure 5.7x28mm ammunition. Do not use +P loads unless specifically approved by the manufacturer, as they may exceed the firearm’s pressure limits.
What is the barrel twist rate?
The barrel has a 1:10 twist rate, which stabilizes standard 5.7x28mm bullets well for accuracy out to 100 yards.
