Top 5 45 ACP Self Defense Ammo

The 45 ACP is an excellent self defense round. It's been in service for the US Military since World War 1. The advantage the 45 ACP has over smaller cartridges like the 9mm Luger is a larger projectile although at a much slower velocity. Most 45 ACP ammo will be between 185 to 230 grains with a velocity between 900 to 1,000 FPS. We've put together our list of top 5 self defense 45 ACP ammo, you can check out all 45 ACP ammo here.

Notice From Hornady: Temporary suspension of nickel plated cartridge cases for Critical Defense® Handgun Ammunition 5/25/21

Unfortunately, everyone is faced with production bottlenecks and supply chains are stressed. In particular, the freight system is delayed longer than normal. Our current turnaround time on nickel plating cartridge cases is 4+ weeks. This delay has created a significant bottleneck in the production of ammunition.

Due to these issues, we will suspend nickel plating on all Critical Defense handgun ammunition to help reduce production time.

Please note, this is a temporary suspension. We will review in six months and plan to resume nickel plating when things return to normal.

This is the absolute best Defensive ammo on the market for most civilian uses. Law enforcement needs barricade/glass penetration but the avg civilian just needs to stop the threat without over penetration. This ammo will do that. I have never had a FTF, FTE, or any problem with this ammo in any of the eight 1911s I have used it in. It also has decent accuracy. Averages 2 inches at 25 yards in most 1911s. In tests on penetration/expansion on water filled one gallon jugs, it penetrated 3 jugs and expanded to 68 caliber. The first jug was completely laid open and the second jug was split clean down the side. The round bulged the back wall of the third jug. That is 18 inches of penetration when fired from 10 yards away. I get the same performance whether it is a 3, 4, or 5 inch barrel. Additionally there is no hollow point on this ammo that can be plugged by denim or leather on initial contact. This stuff always expands due to the polymer tip. I bet my life on this ammo. I also keep the 38 special 110 gr Criti...

Picky gun likes!

I couldn't help but notice this hollow point has a bit more of a taper to the meplat then most. I have an older picky gun doesn't like most hollow points but it fed these just fine. With that said I would gladly recommend these purely based off of reliability.

Great ammo

Consistent expansion but the lead does separate from the jacket unlike some of the more expensive ammo (gold dot etc.) The round is pretty hot and well made. The bullet shape cycles well in my pistol unlike the Gold Dots that have an unusually large hollow point. This ammo is unbeatable for the price.

Underwood Ammunition 45 ACP 174 Grain Lehigh Maximum Expansion Lead-Free Box of 20

While taking advantage of state of the art testing equipment, this high performance ammunition by Underwood is field tested using popular, real firearms that customers are most likely to own out in the real world with all the elements you would experience. If for some reason Underwood Ammunition fails to meet performance expectations, Underwood stands by their product 100% and will make sure the customer is satisfied with every purchase. This ammunition is new production, non-corrosive, in boxer primed, reloadable nickel plated brass cases.

Lehigh’s Maximum Expansion Technology is used to produce projectiles that create the largest wound channels of any bullet you can buy. These cavernous hollow points are designed to expand upon contact with a fluid-based medium through hydraulic energy. They do not expand on dry mediums like wood, drywall, bone, or sheet metal. The expansion process of Lehigh’s Maximum Expansion technology is very different than that of a traditional lead jacketed bullet that expands when it comes in contact with a hard surface – we designed these bullets to expand where the expansion is needed and that is in the vital zone of your intended target. Lehigh Maximum Expansion bullets expand with razor sharp petals positioned and maintained at the largest diameter to provide the greatest cutting surface. Contrast this with a traditional jacketed bullet that expands and quickly mushrooms the nose back along the bullets shank once again reducing the diameter down to a less effective size. Through design and testing, we can move the expansion point and maintain the expansion diameter exactly where required providing the optimum terminal performance. All of Underwood Ammo rounds utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

The Underwood nickel plating process provides several key benefits including; improved feeding in all actions of firearms, enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals. Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass. It was claimed that nickel plated brass casings embrittled the brass therefor making it less desirable for reloaders despite the ease of cleanup that nickel plating offers. In addition, ammunition engineers raising concerns of using nickel plating in very hot +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass.

Features

  • Reduced recoil
  • CNC machined from solid copper to overcome barriers to penetration
  • Large wound channel

Underwood 45 ACP 174 Grain Lehigh Maximum Expansion

I was hesitant to try a New Defense Round. I loved my Proven and reliable HST's. So I decided to do a head to head comparison test. I tested these new Rounds using my FNX .45 Tactical and S&W M&P .45, I tested this for function and against several barriers including 2 layers of drywall, 1/2 in plywood,Laminated Auto glass,Car door into a pork rib and Ballistic Gel back stop, and WOW... long story Short this is my New Everyday Carry round, i will shoot up my supply of HST for practice and start using these. Simply out of this world amazing, see for your self just using 3 1 gallon water jugs filed with water or Jello. I have never seen my Bullet look like the advertized Perfect Expanded round seen in pictures, these really do!!! Largest "gel" wound channel other than a .300 win mag that i have ever seen.
