The Remington New Model Army is a Revolver that is featured in the zombies map Buried. It is functionally equivilant to the Python, but with the ability to reload all six rounds at once. It is slightly weaker than the Python, losing much of its effectiveness at round eleven, but has higher chest and head multipliers when Pack-A-Punched.
When Pack-a-Punched, it becomes the Sassafras and is effective until rounds in the 40s. The magazine size is doubled to twelve rounds and reserve ammunition is increased.
