(https://ammo.com/comparison/44-special-vs-45-acp)

The 44 Special vs. 45 ACP debate has raged for over 100 years, but recently the 45 ACP has dominated the conversation because it offers higher ammo capacity and more ammo options. However, does that mean it’s the right choice for you? As you continue reading, you’ll discover where each handgun cartridge outshines the other.

As an inexperienced shooter, whenever I'd try out a new firearm or cartridge, I was most concerned with how much it kicked. s Now that I'm more experienced (but by no means an expert marksman), I'm less concerned about recoil. But it still factors into some of my decisions. When I'm shooting at the range, I want the experience to be enjoyable. Otherwise, I'll leave that firearm at home.

The 44 Special generates about 4.5 ft-lbs of recoil energy, which is mild and manageable for most shooters. A 44 Special revolver isn't my first choice to hand to a new shooter, but 4.5 ft-lbs of energy isn't a lot even for a handgun cartridge.

The 45 ACP generates about 8 ft-lbs of recoil energy. It's still manageable, but not friendly to newer shooters. One needs to develop proper shooting technique to properly handle recoil while firing a 45 ACP.

I've found both cartridges to be enjoyable at the range, but the 44 Special definitely has less recoil than the 45 ACP. It's important to note that several factors contribute to recoil. The preceding figures are general references and will vary depending on the firearm and ammo you choose.

Stopping Power: Penetration and Terminal Ballistics

These two cartridges are very comparable in terms of stopping power. Both penetrate 12-18 inches in ballistic gel, create similar wound channel diameters (since the bullets are similar in size: 0.451" bullet diameter for the 45 ACP and 0.429" for the 44 Special), and transfer similar amounts of energy to the target. However, the 45 ACP offers many more bullet options that expand better than 44 Special bullets.

Bullet choice significantly affects stopping power. An FMJ will penetrate deeper than a JHP, but a JHP will create a larger wound channel. When we compare similar bullets, the 44 Special has slightly more energy. A 44 Special 180 grain JHP bullet generates 383 ft-lbs muzzle energy, whereas a 45 ACP 185 grain JHP bullet generates 333 ft-lbs.

Accuracy

I've met some incredible marksmen who could outshoot me no matter what cartridge they used. That's because accuracy largely depends on the shooter, and not the cartridge. However, in my experience, it's easier to be more accurate when recoil is lower.

Some shooters find the 44 Special more accurate because it recoils less, but I haven't noticed enough of a difference in recoil to affect my accuracy with either cartridge.

Several factors determine whether a self-defense cartridge is excellent. There's a reason why so many people choose the 45 ACP for self-defense. Those considering modern semi-automatic options often compare 9mm vs 45 ACP for their carry gun.

Since the two rounds' stopping power and accuracy are so similar, the 45 ACP's advantage in ammo capacity and availability is what sets it apart from the 44 Special. The 45 ACP has more self-defense loads available than the 44 S&W Special (more on this in the next section). Ammo capacity is vital during a self-defense situation because you want as many chances to stop the threat as possible. A 44 Special revolver holds 6-8 rounds, whereas a 45 ACP pistol holds 7-18 (depending on which pistol you choose, and noting that drum magazines which hold 40 rounds are also available for the 1911).

The 45 ACP is the better option for self-defense in my (and many other CCWers') opinion.

Cost & Availability

45 ACP firearms and ammo are much more readily available and less expensive than 44 Special firearms and ammo. As of this writing, 44 Special PMC Bronze 180 grain JHP ammo costs $1 per round, whereas 45 ACP PMC Bronze 185 grain JHP ammo costs $0.60 per round. This is just one example of how much more 44 Special ammo costs than 45 ACP ammo. Since the Special carries a premium, it pays to make every round count, so it helps to know the best 44 Special ammo for the job.

More ammo manufacturers produce 45 ACP ammo, which helps ensure there's always plenty on the market and keeps prices relatively low (or at least reasonable).

For budget-minded shooters choosing between the 44 Special and 45 ACP, the 45 ACP is the better choice.

Parting Shots: 45 ACP vs. 44 Special

It's not surprising that these two cartridges have so many similarities, seeing as how they were created within a few years of each other. However, the older of the two (45 ACP) has dominated the battlefield and civilian use, while the younger (44 Special) has seen a drastic decline in popularity over the decades. Both cartridges offer shooters similar stopping power, but the 45 ACP's higher capacity, greater bullet selection, and lower cost have created a devoted fan base that refuses to believe any handgun cartridge is better than the 45 ACP.
