The Crucible Industries Havoc-44 is a six-shot double-action revolver chambered in .44 Magnum, built on a massive stainless steel frame with a six-inch vented barrel. The weapon weighs nearly 1.5 kilograms loaded and produces a muzzle blast that can be felt by bystanders at five meters. Nothing about the Mauler is subtle, moderate, or restrained.

The .44 Magnum round from a six-inch barrel delivers terminal energy that exceeds most semi-automatic pistol calibers by a factor of two or three. Against unarmored targets, the effect is devastating. Against light body armor, the round's sheer energy often defeats protection through blunt-force trauma even when penetration is stopped. The Mauler is the weapon people reach for when they need to put something down and keep it down, regardless of what that something is wearing.

Crucible Industries markets the Havoc-44 with characteristically blunt copy: 'When the problem is big, bring a bigger answer.' The weapon has developed a following among bounty hunters, Shelf enforcers who have saved for years to afford one, and a certain kind of person who believes that carrying the loudest, most powerful handgun available communicates something important about their willingness to use it.
