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 two-inch 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. The 85 Convertible has a removable hammer that twists off for concealed carry and back on for a day at the range. The Ultra-Lite model has an aluminum alloy frame.
