.45 ACP/AUTO Ammo for Sale!

45 ACP, or now 45 Auto is one of the oldest metallic cartridges still in common use today. 45 ACP was developed shortly after the turn 20^th century as the US Military was looking to transition to the newest semi-automatic platforms. Having taken the lessons learned from the Moro Rebellion, the Army Ordinance department required the new sidearm to be chambered in the larger 45 caliber bore diameter to increase effectiveness over the then current-issue 38 Long Colt revolvers. Eventually, the final 45 ACP cartridge ended up firing a 230 Grain Full Metal Jacket projectile at about 850 FPS. After 5 years of development and trials, the 45 ACP Colt pistol, designed by John Browning was adopted and became known as the Model 1911, creating the historic legacy of that particular handgun, and the 45 ACP cartridge. Other notable submissions to the Army trials include a design from Savage Arms, and DWM submitted 2 modified P-08 Lugers. Only one of those pistols is still known to be in circulation, making the 45 ACP Luger is now one of the rarest firearms in existence. It’s reported to have fetched roughly $1,000,000 at auction in 1989, so good luck tracking it down.

The initial Army trials for 45 ACP included the experience gained during the Philippine Insurrection, and shooting a lot of dead cattle. Not exactly scientific by today’s standards, but bullet technology also wasn’t near as difficult to test back in that day and age either. 45 ACP, later designated 45 Auto by SAAMI, quickly earned a reputation for being about as effective as a pistol could be expected to be on the battlefield. While the myth of the “massive” stopping power of the 45 Auto over the 9mm Luger still persists today, modern hollow-point technology have effectively negated any terminal advantage.
