Complete list of parts and technical details

If you want to see all the parts with all the measurements you have to look at the pdf underneath. Based on that info and assuming you have the right tools, you would be able to manufacture your own Colt 1911, which is something I recommend to nobody. But it does contain a lot of interesting information.

Materials

Through the years a lot of different versions of the Colt 1911 have appeared. The main difference between those guns are the use of materials. In the example of the 9mm the most common material is steel. For the grips they used molding plastic. But as you can see in the image below there are different kinds of materials that can be used. In the Colt 1911 Government they used carbon steel for the frame and aluminum for other small parts for example the trigger. And the grips are made out of rosewood.

Safety mechanisms

A very important feature of the gun is the safety mechanisms. They will decrease the number of accidental gun casualties. The Colt 1911 has 3 safety features. The first one is located inside the grip, it blocks the backwards movement from the trigger by blocking it. When the grip safety is pushed the part that blocks the trigger will rotate out of the way enabling the trigger to pass.

The second safety is the most know, the thumb safety. This feature blocks the sear from rotating out of the way. By blocking the sear the hammer will not be able to be released, so it is impossible to fire.

The last safety is located inside the barrel, and is designed to prevent firing when the gun would fall on the ground with the muzzle. The safety blocks the firing pin from passing, only when the trigger is squeezed the safety will release the firing pin.
