The Taurus Millennium PT145 is a compact, semi-automatic pistol chambered in .45 ACP. Known for its small frame relative to its caliber, it utilizes a double-action/single-action trigger system. Factory magazines typically hold 10 rounds, but extended 20-round magazines are also available, increasing firepower. The .45 ACP cartridge provides substantial stopping power.
The combination of a potent cartridge and a compact design made this firearm appealing for concealed carry. This specific configuration offers a significant increase in ammunition capacity compared to the standard magazine, which can be a crucial advantage in certain situations. However, the larger magazine size may also impact concealability. The Millennium series, introduced in the late 1990s, aimed to provide consumers with an affordable, easily concealed handgun for personal defense.
