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.

What does ACP stand for in 45 ACP cartridge?

Answer The Colt .45 caliber automatic pistol was accepted as the standard side arm of the US Army and became identified as the Model 1911 Pistol.

No. The .45 Automatic Colt Pistol (ACP) cartridge is longer the the .45 Glock Automatic Pistol (GAP) cartridge. Since they headspace on the MOUTH of the cartridge case, they cannot be interchanged.


What is the difference between acp and gap?

The .45 GAP is a shorter cartridge than the .45 ACP. Developed for the Glock Automatic Pistol (that's the GAP) it does not interchange with the .45 Colt Automatic Pistol (ACP). Made for a smaller firearm, shorter action, etc.
