The Taurus Millennium series is a product line of double-action only (DAO) and single-action/double-action hammerless, striker-fired, short recoil operated, semi-automatic pistols manufactured by Forjas Taurus S/A (Taurus Forge) in Porto Alegre Brazil. The Millennium line was designed to contend in the civilian concealed carry firearms market, and to be sold as backup weapons for law enforcement officers. Recall In 2015 the PT-111 Millennium, PT-132 Millennium, PT-138-Millennium, PT-140 Millennium, PT-145 Millennium, and PT-745 Millennium were included in the settlement of a lawsuit which alleged that they, and certain other Taurus handguns, could fire accidentally if dropped and that Taurus covered up the safety defects. Without admitting guilt, the company paid $39 million, extended the warranties, and recalled the pistols for repair. Design features 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 are intended to assure that the pistol will not fire if it is accidentally dropped. All Millennium models also include a frame-mounted safety lever. This safety feature was found to fail under some circumstances, leading to a recall. Series 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, 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. Millennium Pro line The Millennium Pro pistols offer many improvements over the standard models, but were introduced as enhancements to the originals, not to supplement them. Pro
