History of 45 Auto (ACP) Ammunition
Introduced in 1905, the John Moses Browning designed .45 ACP was inspired by the U.S. military’s need for a cartridge to replace the “less-than-stellar” performance of the .38 Long Colt cartridge. The .45 ACP was originally introduced with a 200 grain bullet traveling at 900 feet per second. Over the next six years, the .45 ACP along with the M1911 went through testing with the U.S. Army, where modifications were made to both. One major change to the cartridge was the increase in bullet weight to 230 grains, this new bullet weight made the velocity drop to 830 feet per second. This remained the standard load for the service life of the .45 ACP.
Heralded as an excellent man stopper, the .45 ACP was used by Sgt. Alvin York during World War I when he used it to singlehandedly kill 6 German soldiers while assaulting their machine gun emplacements. While one of the more famous stories, York is not the only Medal of Honor winner to wield the .45 ACP. Since its adoption by the military in 1911, the .45 ACP in the M1911 pistol has been carried by no less than 68 Medal of Honor awardees in the course of their heroic actions.
Outside of military service the .45 ACP is used in a wide variety of sporting, law enforcement and personal defense applications. Competitive shooters appreciate the accuracy, mild recoil and heavy bullet that are inherent to the .45 ACP. The major ammunition manufacturers have specialized self defense ammunition that is chambered in .45 ACP. Hornady, Federal and Magtech are a few of the manufacturers that are regularly refining and introducing new ammo for self defense use.
Law Enforcement agencies continue to issue or allow the use of the .45 ACP for their officers and agents. The FBI’s Hostage Rescue Team, LAPD SWAT, and other specialized law enforcement units choose the .45 ACP for its excellent ability to quickly stop dangerous subjects. Although officially replaced in 1985 by the 9mm, the .45 ACP continues to serve in the U.S. Military. The Marine Expeditionary Units, Delta Force and other units of United States Special Operations Command offer pistols chambered in the .45 ACP cartridge as an option for their operators.
The .45 ACP is one of the most modified, analyzed and utilized cartridges in the world. Yet after more than 100 years, it is still one of the most valued cartridges on the market.

"excellent price, service and quick delivery. Just what we all want in a provider. Best part is the price. Next is the fact that you only show what you have in stock, big plus in my book and next is the lightning fast hand off to the UPS guy. I have over 200 rounds already thru my new SR1911 and gun and ammo performed flawlesly, I Shall Return, (remember him). "
- Rick said:
"Purchased 50 rounds, but have only shot 18 so far. I've had no problems at all. Shoots nice and clean, and no duds. I love the federal ammo so far. My only knock was on the value....which I dropped down 1 notch. The price for the 50 round box is awesome, but the shipping and handling hurt the value...still when you can't find the ammo you are looking for locally, the shipping and handling isn't much of an issue. Thank You Ammo.com!!!!"

- Peter said:
"Great performance for the price. A good value."
- Rick said:
"Good Rounds and at a "comparatively" reasonable price to other suppliers gauging prices to take full advantage of a Government incited panic."

"Great target ammo for 1911. Very accurate and clean."
- jim said:
"great ammo, accurate and does what its designed to "
- Jackson said:
"I ordered the ammo for stock, but had to give it a test round or two, Works great"
- Lee said:
"I like the ammo, but not the rising cost of the ammo. No misfires on the ammo in over 500 rounds shot thus far."
- zinger30-06 said:
"This ammo was purchased for range use. I shoot on average 100 rounds per session at least once a week. I was pleasently surprised at the peformance of the round. I fired 25 rounds at one target and then 25 at a second target. Folded them over each other and the groupings were a close match. My carry pistol is a Colt Defender 1911 and this is perfect practice ammo. I will continue to purchase as it becomes available. "
- Louis said:
"Great ammo with high quality brass, also has large pistol primer if you are interested in reloading. As far as value goes, given the recently inflated prices that accompany such high demand all ammo has become too pricey. That having been said, in relative terms it is a great value. It is my go to ammo for practicing."
- Louis said:
"This is reliable, clean burning consistent ammo. It cycles perfectly and there were no malfunctions in either my XDM or my Kimber 1911 super carry ultra. It has high quality reloadable brass with large pistol primers. When available this is my go to ammo."
- Practice said:
"Just purchased this for 1911 range time. Shoots fine through a couple hundred rounds so far with no goofups. Market is up right now so that'll explain overall cost. I'd buy more when the time comes. "
- Snoopy said:
"My only regret is that i didnt buy more than i did. I was just checking different products. These are great. will place another order in a few minutes. Thanks again. Jim Lewis"
- Thom said:
"I cycled 10 round and they fired each and every time. No jamming even in rapid fire. Will buy more as soon as I get the money."
- Hymie said:
"You have my business from now on. Will purchase more after obama quits trying to water down my 2nd amendment rights."
- sarge said:
"Clean firing, no malfunctions. Ammo used to "break in" a new weapon. Accomplished that mission very well, as expected from prior use of CCI ammo."
- Daddy d said:
"Okay, first I will just say I ordered one thousand rounds after doing multiple different tests on this round. I found it to expand over .85" with the biggest one expanding just over an inch. Out of all the premium rounds and the generic rounds on the market for non-bonded hollow points in 45, this had the best performance every....single...time. Not to mention it has light recoil. I found its recoil to be on par with steel cased wolf or tulammo. It fed smooth in my glocks, 1911s and even in my tommy gun. I say buy it. Get it and thank ammo.com for this terrific product. I sure do"
- Sr. said:
"AA++ Thank You for the fast service. "
- Robert said:
"The price and availability are only issues right now. Good ammo."
- Practice said:
"Shot 14 rounds so far to verify cycling. No issues. Will consider this for a carry round. Market is hard and expensive right now."
- DJS said:
"I was impressed with the ammo I purchased for you. The price was right."
- Dayne said:
"1st time shooting this new pistol, Smith &Wesson, M&P, 4" barrel. 1st was the target ammon to get used to it then full mag of the Remington. Very accurate even in rapid fire. 6 out of 10 in 4" circle. Other 4 within the 6" circle. In other wards, all round placement, terminal. "
- joe said:
"The only thing that could have been better is the price, but with everything that is going on with gun control the price was still acceptable. Thank You and i will be purchasing more in the fucture"
- Jim said:
"Thanks for the quick service. This ammo ran flawlessly thru my 1911 gold cup and my grandson's glock. We both fired over 600 rounds each during the handgun course we attended."

"I yet to shoot the ammo I purchased ,I am being very conservative on range time, watching the current market and trying to get a better understanding on what is unfolding before us.God be with you ,I preach the 3 G's..God,Guns and Gold..MOLON LABE... P.S gave ratings for the fact that you are from the great state of Georgia and the soul of America..the South has my heart"

"I just bought a S&W 1911 E series 41/4" and took it with a box of The Federal 230 HP to the range. At 8 paces, I shot a consistent 4" 7 round group. First time shooting a 45 and with this ammo. I am very certain that the consitancy of this ammo was top notch. I was a big fan of 9mm, but I now have a new love for 45's, after all they are bigger than 40's. I wish I had bought more."
