Anyone who knows the Grizzly will just remember the Mk V version, which is the .50 AE variant to compete with the Deagle. But before the Mk V, were a slew of different variations that uses other calibers.
The Mk IV however, uses .44 Magnum. Yes, a .44 Magnum pistol!
The LAR Grizzly Mk IV has most of the format, handling and layout similar to the MK V, with the difference between the barrel and magazine follower, otherwise, the oversized 1911 is made strong enough to fire larger rounds.
Comes with 7 round magazine, as well as the ability to mount pistol stock and muzzle devices.
