Key Features

• Optic-Ready Serrated Slide — Ships with a removable cover plate, so you can mount a red dot without sending the slide out. Cuts setup time for carry optics.
• Threaded 4.80-Inch Barrel with Thread Protector — Ready for a suppressor or compensator out of the box. The 1/2×28 threads are common, so finding accessories is easy.
• 23+1 Round Capacity — That’s two extra rounds over the standard 17-round M&P9 magazines. Fewer reloads in a defensive or competition scenario.
• Four Interchangeable Palmswell Grip Inserts — Small, medium, medium-large, and large. Adjust the grip circumference to fit your hand without changing the backstrap.
• Rigid Metal Frame Chassis — The steel insert locks the trigger group and slide rails into a single rigid unit. Improves consistency shot to shot.

Who It’s For

This one’s for the EDC crowd who run optics and suppressors, or want the option to. If you carry a full-size pistol under a jacket or in a duty holster, the 23+1 capacity and threaded barrel make it a serious tool. It’s also a strong pick for USPSA Carry Optics or Limited division shooters who want a factory gun that’s ready for a dot and a comp.

Pros & Cons

• Pro: High capacity (23+1) without aftermarket base pads.
• Pro: OD Green Cerakote holds up well against holster wear.
• Pro: M&P M2.0 trigger has a shorter reset than Gen1 M&Ps.
• Con: The factory trigger pull is around 5.5–6.5 lbs, which is heavier than some aftermarket options. A drop-in trigger kit can fix that, but it adds cost.

The Zev and Agency guns cost more and ship with lower capacity. The 14646 gives you more rounds and a threaded barrel for less money, though the trigger won’t feel as refined as a Zev’s out of the box.

FAQ

Does the Smith & Wesson 14646 come with a threaded barrel?

Yes. It ships with a 4.80-inch threaded barrel (1/2×28) and a thread protector. It’s suppressor- and compensator-ready from the factory.

What optics fit the M&P9 M2.0 optic-ready slide?

It uses the M&P CORE footprint. You’ll need a specific adapter plate for Trijicon RMR, Holosun 407C/507C, Leupold DeltaPoint Pro, or Shield RMS. The pistol ships with the cover plate installed.

How many magazines are included?

Two 23-round magazines come in the box. They are full-size 9mm M&P M2.0 magazines with a slightly extended basepad.

Is the OD Green Cerakote durable for daily carry?

Yes. Cerakote is a ceramic-based finish that resists scratches and corrosion better than standard bluing. The OD Green color hides holster wear better than black.

Can I use standard M&P9 holsters with the threaded barrel?

Most holsters with an open muzzle end or a threaded-barrel option will work. Check the manufacturer’s fitment notes for M&P9 M2.0 with threaded barrels. Some closed-end holsters may not accommodate the extra length.
