A powerful handgun chambered for the .454 Casull cartridge, this firearm type features a semi-automatic action, meaning it automatically loads a new round after each shot. This contrasts with revolvers traditionally used for this high-pressure cartridge. The design offers a larger magazine capacity than revolvers, generally enabling faster follow-up shots.
This type of firearm presents advantages for hunters seeking potent stopping power against large game. The semi-automatic mechanism reduces recoil compared to similarly powerful revolvers, theoretically improving accuracy and shot recovery time. Its higher ammunition capacity is also beneficial in hunting scenarios. The development of such firearms represents an evolution in handgun technology, bringing the .454 Casull cartridge into a platform previously dominated by revolvers.
