Top 5 45 ACP Self Defense Ammo

Hornady Critical Defense Ammunition was purpose built for concealed carry guns and designed to deliver reliable and controlled expansion regardless of target every time.. Critical Defense Ammunition is loaded with Hornady's  bullet which has a soft polymer insert that delivers superior controlled expansion and large, deep wound cavities over a wide range of velocities. Each round is loaded into a nickel case for increased visibility in low-light situations and premium low flash propellants that deliver proven performance, even in very short-barreled handguns that will not disrupt your vision. This ammunition was designed by Hornady to expand every single time. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Features

• Unaffected by thick and heavy clothing, including denim and leather
• Bullet delivers superior controlled expansion and large, deep wound cavities over a wide range of velocities
• Clean burning and efficient propellants reduce recoil in lightweight handguns, and perform consistently at all temperatures
• Minimal muzzle flash protect night vision
• Feeds reliably in pistols
• Bullets are custom designed for individual loads
• Effective, consistent, reliable self-defense ammunition

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. We will resume nickel plating when things return to normal.

Federal Premium Hydra-Shok has proven itself for self-defense since 1989. Hydra-Shok Deep builds off the time-tested platform with design improvements that better meet modern performance measurements. The bullet features a more robust center post and a core design that provides as much as 50 percent deeper penetration than original Hydra-Shok and competitor loads. This ammunition is new production, non-corrosive, in boxer primed, reloadable nickel plated brass cases.

Features

• Penetrates 15 inches in bare ballistics gel—the optimal depth according to FBI standards
• 50 percent deeper penetration than original Hydra-Shok
• 70 percent improvement in FBI protocol score
• Iconic center post design has been improved for better, more consistent expansion through standard barriers.
• Consistent, specially formulated propellant
• Extremely reliable Federal primer

SIG V-Crown defensive rounds combine perfected material specifications and fine-tuned design innovations, including a stacked hollow point cavity, to deliver exceptional on-target energy with maximum weight retention and optimal expansion for ultimate stopping power. SIG V-Crown ammunition creates a consistent V-shaped main cavity on top of a deep narrow trail with superior weight retention, maximum expansion, optimal penetration depth time after time. This ammunition is new production, non-corrosive, in boxer-primed, reloadable nickel-plated cases.

Features

• Designed to match Sig Full Metal Jacket ammunition
• High Quality components
• Reloadable nickel-plated brass cases

Note: Due to availability of components, this ammunition may or may not be shipped in nickel plated brass.

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

Winchester USA Ready Defense ammunition is a select grade of ammunition and components, designed for personal defense. Made in the USA, it offers the ideal combination of stopping power, penetration and reliable expansion. The unique Hex-Vent Rigid Insert shields the hollow point from obstruction while channeling material flow for positive bullet expansion. This ammunition is new production, non-corrosive, in reloadable nickel plated brass cases.
