The Millennium Pro pistols offer many improvements over the standard models, but were introduced as enhancements to the originals, not to supplant them. Pro counterparts have now been released for nearly all of the original models. Some features of the Pro line include optional increased magazine capacities, larger and easier to operate controls, a single action/double action trigger mechanism on some models with reduced trigger travel and an improved smoother and lighter trigger pull, an enhanced frame, and an improved more ergonometric grip design. Key to the grip upgrade are recesses which Taurus call 'Memory pads', intended to promote a consistent shooting grip from shot to shot. Other Pro improvements include the contrast enhanced Heinie ‘Straight-8’ sighting system, as well as optional night sights, a loaded chamber indicator which can be felt as well as seen, and a feature labeled 'posi-traction' which consists of an alteration to the number and layout of the slide serrations resulting in an improved gripping surface.
Taurus Millennium series pistols are manufactured with injection molded polymer frames, and blued carbon steel, stainless steel, or titanium slides. Available cartridge chamberings include .32 ACP, .380 ACP, 9mm Parabellum, .40 Smith & Wesson, and .45 ACP. Magazine capacities vary between 6, 10, and 12 rounds depending on model and caliber. The Millennium line includes several innovative safety features including a positive firing pin block as well as the "Taurus Safety Latch", a transfer bar safety which prevents firing of the pistol unless the trigger is pulled. Together these safeties assure that the pistol will not fire if it is accidentally dropped; selected models have been certified as satisfying the California Drop safety requirement. All Millennium models also include a frame-mounted safety lever.
Three distinct series, or generations, of Millennium pistols have been produced. The 1st series featured double action only triggers and a 10 round magazine capacity. The 2nd series resulted from a complete redesign of the 1st, offering a less ergonomic and visually pleasing design, but retaining the double action only trigger system. The 2nd series also introduced the 'Taurus Security System' (TSS), the Taurus version of an Integrated firearm locking safety system, as well as the enhancements Taurus categorizes as the Millennium ‘Pro’ package. The 3rd series added single/double action triggers on several models in lieu of the double action only of the first two series. Additionally, the grips of 3rd generation pistols are available in various different colors and the grip stippling is altered; tactical or Picatinny rail accessory mounts are also an option.
