- "The M3 pump shotgun is devastating at close range, but spreads easily over distance."
- ― in-game description
The M3 (Super 90) is a dual-mode shotgun designed by Benelli, an Italian firearms manufacturer. Being dual-mode, the M3 can be used as both a semi-automatic and pump-action shotgun. The M3 is an improved variant of the M1 shotgun.
The M3 shotgun, a variant of the Benelli M1 and M2 shotguns, is a dual-mode shotgun that features the ability to switch to both semi-automatic and pump-action modes quickly. Known for it's versatility and reliability, the M3 shotgun is also designed with a removable stock for customization. The M3 shotgun can use either 12 or 20-gauge shotgun shells, the pump-action mode used mostly for rubber ball rounds and non-lethal ammunition.
In Tom Clancy's Splinter Cell: Conviction, the M3 is strictly a pump-action shotgun (the player is unable to switch between modes); it is available from the "Exlusive Content" section. In the game, the M3 fires buckshot rounds and offers superior close range combat damage, but the spread makes it's aim poor at mid- to long-range. It does more damage than the M500, but has a shorter lethal range. It can be upgraded w ith a 2x scope, match grade ammo and a laser sight. As with the SPAS-12, the 2x scope attachment is not of good use considering the spread and poor range, along with the fact attachments cannot be removed after purchase. Match grade ammunition slightly increases the effective range of M3 but the difference is not much to notice.
|2X Scope||300 points|
|Match Grade Ammo||250 points|
|Laser Sight||250 points|
- Despite having the ability to switch between dual-modes on the real-life M3, the M3 in Conviction is ONLY pump-action operated.
