Its formal designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original Model of 1911 or Automatic Pistol, Caliber .45, M1911A1 for the M1911A1, adopted in 1924. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam era. Above taken from Wikipedia the free online encyclopedia. The M1911 has a low and narrow front and rear sight; Curved Flat Mainspring Housing; No Finger Recess behind the trigger; Narrow-Depth Triger; High-Wall Ejection Port; Wide Hammer; Smaller Grip-Safety and some other slight differences. The M1911A1 has a taller and thicker front and rear sight; Round Mainspring Housing; Longer Trigger; Lanyard Loop (May be on M1911 also); Finger Recess behind trigger; Spur Hammer; Longer web-spur on Grip Safety; Heat Treated Forward Upper Reciever; Lowered Ejection Port; Plastic or Walnut Grips. The key differences are the smaller sights on a M1911 upper reciever, and the mainspring housing. These are commonly known as Series-70 models, because they don't have any extra firing pin safety levers. Series-80 models (From Colt), have an internal transfer mechanisim that uses the trigger's rearword force to actuate two small levers that depress a stop plunger in the upper reciever's firing-pin port, that allows the firing pin to move freely when the hammer falls. Kimber's use a very similar, but better designed internal release, that uses the grip safety as a motivator for the firing pin stop. Other companies, like Springfield, use manual locks that prevent the mainstring plunger from moving when the hammer is cocked (The hammer spur moves downward to compress the mainspring. Lock the mainspring plunger and the firearm cannot be cocked. This is not a passive safety, but another method of making an already safe weapon even less reliable, to solve a problem that never existed in the first place... )

Who invented the Colt 45?

The M1911 is a single-action, semiautomatic handgun chambered for the .45 ACP cartridge. It was designed by John M. Browning, and was the standard-issue side arm for the United States armed forces from 1911 to 1985, and is still carried by some U.S. forces. It was widely used in World War I, World War II, the Korean War and the Vietnam War. Its formal designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original Model of 1911 or Automatic Pistol, Caliber .45, M1911A1 for the M1911A1, adopted in 1924. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam era. In total, the United States procured around 2.7 million M1911 and M1911A1 pistols during its service life.The M1911 is the most well-known of John Browning's designs to use the short recoil principle in its basic design. Besides the pistol being widely copied itself, this operating system rose to become the pre-eminent type of the 20th century and of nearly all modern pistols.For the source and more detailed information concerning your request, click on the related links section indicated below.

When was 45 automatic pistol invented?

If by 45 automatic pistol you mean the 1911 Colt, then John Browning developed this design and the cartridge it uses between 1900 and 1904, producing his first prototype for testing in 1904. It was tested and modified, then adopted for service use by the United States in 1911, hence its designation as the M1911 Automatic Pistol. The design was further modified to create the M1911A1, which includes the grip safety.
