The Mossberg 500 (also known as the M-500) is a pump-action shotgun developed and designed by firearms manufacturer O.F. Mossberg & Sons.
The Mossberg 500 is a pump-action shotgun, first introduced in 1961 and each variant primarily based on the same design. The Mossberg 500 is very popular, being the top-selling shotgun.
In Tom Clancy's Splinter Cell: Conviction, the Mossberg 500 is the only shotgun available in the standard edition of the game, appearing right at the start of the single-player campaign first used by Dmitri Gramkos and later on in most of the single and multiplayer missions, players can find enemies carrying the M-500 shotgun.
Although it is a pump-action weapon, the M-500 can be fired very rapidly, and is usually lethal with just one shot at close range. It's power decreases dramatically at intermediate ranges, as does its accuracy. One difference between yours and your enemies' shotgun is you can see several projectiles being fired from your shotgun, while the enemies' only have one (the "one" is still accurate however). Due to the M-500 being unsuppressed like other shotguns, it is very conspicuous when fired. If the shot doesn't kill, the enemy will be knocked down for a short period. It can be upgraded with a reflex sight, a laser sight, and match-grade ammunition, though the latter two provide little practical value given the shotgun's inherent inaccuracy.
|Reflex Sight||400 points|
|Laser Sight||250 points|
|Match Grade Ammunition||250 points|
- The M-500 is the third usable shotgun in Splinter Cell series, before that was shotgun attachment for SC-20K M.A.W.S. in both Tom Clancy's Splinter Cell: Chaos Theory and Tom Clancy's Splinter Cell: Double Agent. The second shotgun was the non-lethal FN-303 Riot Shotgun in Double Agent.
