Description
The 5.7x28mm cartridge is a blast to shoot, and the M&P 5.7 gives it a proper home. Smith & Wesson built this full-size pistol around their Tempo barrel system, a gas-operated, locked-breech design where the rotating barrel stays locked until the bullet passes the gas port. What that means at the range is a noticeably soft-shooting pistol with very little muzzle rise, which pairs nicely with a round that was already easy on the hands to begin with. Add a 22+1 capacity and you can run drills for a good while between mag changes.
What Sets the M&P 5.7 Apart
This is an internal hammer-fired, single-action pistol, and the flat-face trigger breaks clean with consistent finger placement shot after shot. The 5-inch stainless steel barrel wears a corrosion-resistant Armornite finish, carries a 1:9 twist, and comes threaded 1/2×28 with a thread protector installed, so adding a muzzle device is simple. Up top you get steel 3-dot sights and an optic-cut slide with forward serrations, and down below there is a Picatinny-style rail for a light or laser. The whole package wears a Flat Dark Earth Cerakote finish that looks sharp and holds up to real use.
Built for Righties and Lefties Alike
Smith & Wesson kept the ergonomics practical. The grip is slim and well textured, which makes a 22-round pistol feel much more manageable in hand than the capacity would suggest. An ambidextrous slide stop and reversible magazine release mean left-handed folks are not an afterthought, and this version skips the thumb safety for a cleaner draw stroke.
Why the M&P 5.7 Earns Range Time
At 26.7 ounces with an 8.5-inch overall length, it balances well and points naturally. Whether you are chasing steel, introducing a recoil-sensitive shooter to centerfire pistols, or just want something different in the safe, this one delivers. Two 22-round magazines come in the box, so you are ready to load up and go from day one.

Frequently Asked Questions
What is the Tempo barrel system on the M&P 5.7 and why does it matter?
Tempo is Smith & Wesson's gas-operated, locked-breech design that uses a rotating barrel. The barrel does not cam open until the bullet passes the gas port, which keeps things locked up longer for better consistency and takes the edge off recoil. Combined with the naturally soft-shooting 5.7x28mm round, muzzle rise is minimal and follow-up shots come fast.
Can I mount a red dot on the Smith & Wesson M&P 5.7?
Yes, the slide comes cut for optics from the factory, and it works with popular micro red dots that use the RMSc-style footprint. The steel 3-dot sights are there whether you run an optic or keep it irons-only. Forward slide serrations also make press checks easy with an optic mounted.
Does this M&P 5.7 have a thumb safety?
No, this is the no-thumb-safety version (model 14004). It relies on a trigger safety and internal safeties instead, which many folks prefer for a snag-free, simpler manual of arms. Smith & Wesson does make a separate variant with a manual thumb safety if that is more your speed.
Is the M&P 5.7 suppressor ready out of the box?
The 5-inch barrel is threaded 1/2×28 and ships with a thread protector installed, so it accepts common muzzle devices and suppressors using that thread pitch without any gunsmithing. The tall steel 3-dot sights and optic cut give you flexible aiming options when running a can. Just spin off the protector and you are set.
