- Tactile loaded chamber indicator lets you confirm chamber status by feel without breaking your grip or your eye from the target
- Reciprocating cover with a dedicated release button speeds up the clearing of damaged or stovepiped shells
- Each magazine tube features individual assist buttons for faster and easier loading and unloading under stress or time pressure
- M-LOK barrel shroud gives you a modular mounting platform for lights, foregrips, and other accessories along the full length of the forend
- The M&P pistol grip ships with four palmswell inserts so you can fit the grip precisely to your hand size and shooting style
- Ambidextrous controls throughout, including the safety selector and magazine tube buttons, make the shotgun fully functional for left-handed and right-handed shooters without modification
Practical Benefits
- The bullpup layout puts the action behind the trigger group, which means you get a 19-inch barrel in a platform short enough to move through doorways, vehicles, and tight spaces that would stop a traditional shotgun cold
- Switching between tube loads mid-engagement takes only a button press, so you can go from buckshot to slugs or from 3 inch to 2-3/4 inch on demand without unloading
- The M-LOK shroud lets you build the forend out to fit your role, whether that means a mounted light for low-light environments or a foregrip for added control
- The Remington-pattern choke compatibility means you can source replacement and specialty chokes from a wide selection of aftermarket suppliers
- Your choice of palmswell insert lets you dial in a grip that fits the way you actually shoot, not a one-size-fits-all solution
The Smith and Wesson M&P12 Bullpup Pump-Action Shotgun (12490) in 12 gauge is a capable tool for the home defender or tactical shooter who demands high capacity and true compactness in a proven pump-action platform.
