Chrome Shotgun

"This shotgun 'l'work."

The Chrome Shotgun is a pump shotgun variant in Left 4 Dead 2. The tight spread of 8 pellets in each shell make it capable of taking out Infected at moderate ranges in addition to being a powerful close range weapon, and each shot penetrates Infected indefinitely. This often makes it better at handling hordes than the submachine gun or pistols.

Differences
The chrome shotgun has a significantly tighter spread and lower recoil than that of the pump shotgun. It also has fewer pellets, with each individual pellet doing more damage, although its maximum damage is slightly lower than the pump shotgun's. Both weapons reload at the same rate but the chrome shotgun seems to fire slightly faster than the pump shotgun.

Tactics

 * The chrome shotgun's accuracy makes it great for taking out Special Infected from a safe distance.
 * Shoot at Infected mobs running in a fairly straight line to get multiple kills.
 * Like with the other shotguns, reload the chrome shotgun as frequently as possible.
 * Due to the somewhat small reserve of the chrome shotgun, try to avoid wasting ammo whenever possible.
 * If you have Incendiary/Explosive Ammo for this weapon, switch to your secondary weapon unless a horde arrives. The spread of the shotgun is just big enough that it can light up a crowd of enemies in a couple of shots.
 * Witches can be easily crowned with the Chrome Shotgun because of its tighter spread.
 * By equipping a laser sight the Chrome Shotgun gains a lot of Range per shot. This range can rival that of a tier 2 shotgun and even the AK-47.

Trivia

 * The shotgun's animation, instead of pumping downwards due to recoil, now seems to resemble Team Fortress 2's shotgun pump animation, but slower.
 * This gun is actually that of a Remington 870, most likely a NICKEL, not chrome Marine model, examination of the placement of two screws above the trigger guard and the lengthy ammo tube and the utter lack of the hammer that is exposed near the stock of most Mossberg 500/590 models proves that, the plastic/rubber pump is smooth with a thumb grip, designed for shoulder fire like most Remingtons. The vent rib above the barrel usually denotes it's for hunting and sport which also explains the tighter spread as there is probably a barrel choke embedded in the barrel, and the Ghost ring sights are an aftermarket add-on. As most law enforcement/military institutes don't have a nickel/chromer-6 budget to keep their guns shiny, and judging the from the fact that they're in the south, a place where the 2nd amendment is a big issue, it's likely of civilian origin.
 * This is a Model 870 magnum "marine" type, the bright satin finish on the metal work helps prevent corrosion in salt environment, and as the south is located next to the ocean, this would be a good choice for a gun. this makes sense it is a Remington, as the pump shotgun from the original l4d is a 870 slug gun, with short barrel and magazine.
