Stagecoach

Description
The Stagecoach is the game's most powerful and expensive shotgun. What it lacks in capacity (being a double-barrel shotgun), it makes up for in relative accuracy, raw damage, and quick fire rate. It can easily 1 shot kill in close range, and can 2 shot out to medium range if the spread is forgiving. It has an RPM of 480, and a reload speed of 1.5 seconds for both shells.

It is expensive, but useful in cases when the Benelli M4 doesn't provide enough damage at long enough ranges.

The close-range one-shot capability may get you called a hacker, regardless if you are actually cheating.

Trivia
Its multiple projectiles all bounce at least once, making it useful for killing enemies behind cover, namely around the police-only room in the treasury.

It loads 2 shells, and carries 36 in reserve. A full ammo refill costs $5,000.
