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. Millennium G2 In early 2013, Taurus introduced a new G2 model to the Millennium pistol series. The G2 features stippled texturing on the grips, replaces the slide retainer pin with Glock-style pulldown tabs to disassemble the firearm. The Millennium G2 retains the same loaded chamber indicator as the prior Pro models, but replaces the Heinie ‘Straight-8’ sighting system with adjustable 3-dot sights. The Millennium G2 comes in two models, the PT111 chambered in 9mm, and the PT140 chambered in .40 caliber. The G2 models are rated for +P loads. Since then, Taurus has introduced their G3C model, the same size as the G2, and their new G3 full size model. Model designations Taurus Millennium line model designations consist of 3 digits followed by 1 to 3 characters, which in turn may be followed by an optional third sequence of a dash and 2 digits. The leading three numerals indicate the model's cartridge chambering, for example, number 132 represents .32 ACP chambering, 138 corresponds to .380 ACP, 111 signifies 9 mm Parabellum models, 140 denotes the .40 S & W offering, and 145 indicates .45 ACP chambering. An optional 'P' character trailing the chambering digits indicates whether the pistol is a ‘Pro’ model, and the next 1 or 2 characters denote the slide composition. A ‘B’ indicates blued steel, the characters ’SS’ indicate stainless, and a 'Ti' signifies titanium. The optional final hyphenated number at the end of the model designation (either a -10 or -12) indicates an extended magazine capacity. Thus the model number 111BP-12 would indicate a 9 mm Millennium Pro pistol in blued
