"I guess it'll do. Yeah, whatever, it's a machine gun."

The Silenced Submachine Gun is a Submachine Gun variant in Left 4 Dead 2. It holds 50 rounds with 650 in reserve, although it burns through ammunition quickly due to its high rate of fire. The Silenced Submachine Gun has greater stopping power than the normal Submachine Gun, but has lower accuracy and higher kickback that makes it a poor weapon for long distance shots.

Pros

 * Stronger than the regular Submachine Gun.
 * Fast rate of fire allows it to rip up hordes and Special Infected that are close.
 * If using burst fire it isn't too hard to conserve the good amount of ammo.
 * Using the laser sight on the Silenced SMG helps a lot with accuracy.
 * Can penetrate through walls and doors.

Cons

 * It is not very powerful against a Tank or Witch. Doing even less than the weakest shotgun, the Chrome Shotgun.
 * It is awful at long range shooting.
 * Using full auto shooting with no trigger discipline will leave you out of ammo in seconds.
 * It needs to reload often if you don't use burst fire.
 * It's not all that much better when using incendiary or explosive rounds.

Tactics

 * Fire in short bursts to conserve ammunition, as it's easy to burn through your ammunition quickly.
 * The lower accuracy of the Silenced SMG requires you to crouch to get any shots at medium range. Avoid shooting long-distance targets, as it's usually a waste of bullets.
 * The Silenced SMG tears through hordes efficiently, as the lowered accuracy doesn't hurt as much.
 * A Magnum works well with a Silenced SMG, giving you a useful long range secondary weapon to pick off Special Infected with, although you can pick up a melee weapon to save ammunition as well.
 * The Laser Sight helps the Silenced SMG significantly, allowing it to pull off longer-distance shots much more easily and take out Special Infected with greater precision.
 * Explosive ammo and Incendiary ammo do not benefit the Silenced SMG as much as they do the Regular SMG, as the Silenced SMG's lower accuracy makes it more difficult to get the most out of the upgrade magazines, and the Silenced SMG has more stopping power anyway.
 * Since it's Silenced, Silent kills are unnessecary, but when firing at Commons/Uncommons roaming around the place, other Infected won't hear the shots. Useful on Expert skill.
