Ultra-fast, ultra-reliable, and ultra-lightweight Model 85 revolvers are the most popular family of guns that Taurus produces. They pack them with a combination of customer-requested features and pair them with the .38 Special +P ammo, making them powerful, easy to carry, and lightning-quick to use. The snub-nose 85 has a shortened barrel and weighs only a pound. A transfer bar mechanism prevents the hammer from striking the firing pin unless the trigger is pulled fully to the rear and the Taurus Security System consists of a keyed, quarter-turn style socket-head screw which can be set to prevent the hammer from pivoting back into the frame, thus rendering the weapon inoperative. This model has a 1" titanium barrel, yoke, and cylinder; an aluminum alloy frame; and bull logo polymer grips.
