Description
The Smith Wesson MP 5.7 FDE is the high-capacity, threaded-barrel version of Smith & Wesson’s 5.7 pistol, finished with a flat dark earth frame under a black slide. Twenty-two rounds of a cartridge that barely recoils, a threaded muzzle and an optic cut make this one of the more capable range pistols on the shelf, and it ships with two magazines rather than the usual one.

Why the Smith Wesson MP 5.7 FDE Shoots So Easily
This is the configuration people buy the M&P 5.7 for. Twenty-two rounds in the magazine, two magazines in the box, and a cartridge so mild that a full magazine goes by without your grip breaking down. The Smith Wesson MP 5.7 FDE is a genuinely easy gun to shoot well, which is not something you can say about most full-size pistols with this much capacity.
Five-seven sends a light bullet very fast, so trajectory is flat and holds are simple out to distances where 9mm needs thinking about.
Threaded Barrel and What It Opens Up
The muzzle is threaded, and rimfire-adjacent cartridges like 5.7 are among the more rewarding things to suppress. That route is a federal NFA process: an ATF Form 4, a two hundred dollar stamp, months of waiting, and state legality. We do not sell NFA items, so a can has to come from a dealer holding an SOT. A thread protector covers the threads otherwise.
A brake is the simpler option, though on a gun that recoils this little there is not much left to tame.
Thread pitch on the Smith Wesson MP 5.7 FDE is the standard 1/2×28 used across the cartridge, so mounts and protectors are easy to source.
Optic Cut, Rail and the FDE Finish
The slide on the Smith Wesson MP 5.7 FDE is optic ready, so a red dot mounts without milling — and a dot suits this cartridge particularly well given how flat it shoots. A full-length Picatinny rail takes a duty light. The flat dark earth Cerakote on the frame contrasts with the black Armornite slide, which is the two-tone look this model is known for.
This configuration has no thumb safety, which some buyers prefer and others specifically do not.

Who the Smith Wesson MP 5.7 FDE Is For
Range shooters and enthusiasts, mostly, and people building toward a suppressed setup. It is also a strong home-defense option for a household where not everyone is a confident shooter — low recoil and twenty-two rounds is a forgiving combination. Anyone who already owns a 5.7 carbine gets ammunition commonality.
If you want a thumb safety, the standard M&P 5.7 with a safety is the version to buy instead.
Competitors and high-volume range shooters like the Smith Wesson MP 5.7 FDE because a long session does not wear the hand out.
Ammunition: The Real Consideration
Five-seven costs more per round than 9mm and is stocked in fewer places, and that is the honest running cost of owning the Smith Wesson MP 5.7 FDE. Supply has improved considerably as more makers have entered the market, but it is still worth buying in quantity when you see it priced well.
Function-test anything you plan to rely on. Some ranges also restrict 5.7 on steel because of velocity.
Magazines, Holsters and Setup
Two 22-round magazines ship in the box, which is unusual and worth noting when you compare prices against other pistols. Holster selection for the M&P 5.7 is narrower than for a 9mm M&P, so confirm a maker lists this model. Most owners of the Smith Wesson MP 5.7 FDE shoot it at the range rather than carrying it.
Check your state magazine rules before buying spares.
We can fit an optic to the Smith Wesson MP 5.7 FDE before it ships if you buy the dot with the pistol.
