The Taurus Raging Bull .500

The Raging Bull is a revolver manufactured by the Brazilian Taurus International firearm company.
In its larger calibers it is marketed as a hunter's sidearm because it is a potent weapon with plenty of stopping power. The .454 Casull cartridge has been used to hunt animals as large as Cape Buffalo[1] and African elephants.[2]
The Raging Bull has a thumb ported barrel and a red rubber strip along the back of its grip, which cushions the shooter's hand and lowers perceived recoil. Functionally, the Raging Bull has a manually operated front cylinder latch, whose release can be seen on the crane in the picture. Front cylinder latches are required for such high powered double action revolvers, and are found on the Ruger Super Redhawk and the S&W Model 500 revolver, but they are actuated by the rear cylinder latch. The manually operated latch on the Raging Bull is simpler (and thus less expensive to produce) yet equally strong but requires two hands to open the cylinder.
