MIL Thunder 5

The MIL, Inc. Thunder 5 is a large, double-action revolver chambered in the .410-bore shotshell cartridge. It is also designed to fire the .45 Long Colt revolver cartridge. The revolver, somewhat unusual for the type of weapon, features a manual safety lever.

As the barrel is rifled, the Thunder 5 is not considered a short-barrelled shotgun under United States federal law, but is under California statutes. However, a variant was produced in .45/70 Government that is legal in the aforementioned state. Production of the .45/70 variant started in 1994.

Sub-caliber sleeve inserts in 9mm Parabellum, .38 Special/.357 Magnum and .38 Super were produced and available until 1998.
