The primary differences between .380 ACP and .38 Special are:<\/p>\n
- \n
- .38 Special is a longer cartridge<\/li>\n
- .380 is rimless while the .38 Special is rimmed<\/li>\n
- they have similar bullet diameters<\/li>\n
- .38 special is designed for use in revolvers and the .380 ACP is used in semi-auto pistols<\/li>\n<\/ul>\n
.380 vs. .38 Special Similarities<\/h2>\n
Right off the bat, instead of comparing .380 vs. .38 Special, it’s tempting to compare .38SP to 9mm instead. However, that’s 1) been done, and 2) there are a lot more parallels between .38 Special and .380 ACP than you’d think.<\/p>\n
For example, a Hornady Critical Defense Lite 90 grain 38 Special<\/a> round is going about 900 feet per second out of a 2-inch revolver barrel. The Hornady Critical Defense 90 grain 380 ACP<\/a> is going…about 900 FPS out of a Glock 42. Two projectiles of identical weight with identical muzzle velocities, but two different calibers.<\/p>\n
Which is Better: .380 vs. .38 Special<\/h2>\n
Now that we’ve established they’re similar, let’s figure out which is better: .38 Special or .380 ACP.<\/p>\n
.380 vs. .38 Special Guns<\/h3>\n
![\".38](\"https:\/\/www.targetbarn.com\/broad-side\/media\/38revolver.jpg\" "\\".38")
Compact, lightweight revolvers, like the S&W AirLite, are easy to conceal but can be more difficult to shoot.<\/figcaption><\/figure>\n First, let’s look at the platforms the rounds use most frequently. For the humble .38 Special, the most common launcher is going to be a small, compact, lightweight revolver<\/a>. These are great guns to conceal, but usually have lousy sights and heavy trigger pulls.<\/p>\n
Similarly, the most popular .380 on the planet is the Ruger LCP<\/a>, which has lousy sights and a heavy trigger pull.<\/p>\n

The Smith & Wesson M&P Shield EZ .380 ACP is easy to shoot.<\/figcaption><\/figure>\n Both calibers do have options that are easy to shoot. For .38 Special there’s the excellent 3 inch Ruger LCR<\/a>, which has good sights and a good trigger. In .380 ACP, the Glock 42<\/a> is the stand-out. The S&W Shield EZ<\/a> and Beretta 84 are also easy to shoot. All this tells us is that the platform selection is a wash.<\/p>\n
.380 vs. .38 Special Ballistics<\/h2>\n
If the platforms are basically equal, it comes down to the cartridge. Instead of relying on anecdotal reports, we can turn to science.<\/p>\n
.38 Special Ballistics<\/h3>\n
![\".38](\"https:\/\/www.targetbarn.com\/broad-side\/media\/38spballistics.jpg\" "\\".38")
Three rounds of Winchester .38 Special 130gr. PDX1 Defender +P in ballistic gel.<\/figcaption><\/figure>\n Independent ballistic testing showed the following results for 5 common choices of .38 Special ammo for sale<\/a> when fired from a 2-inch barrel:<\/p>\n
- \n
- Federal 110gr. Hydra Shok<\/a>: 13 inches of penetration and no expansion<\/li>\n
- Hornady 110gr. Critical Defense<\/a>: 13 inches of penetration and expanded to .44 inches<\/li>\n
- Remington 125gr. Golden Saber +P: 14 inches of penetration and expanded to .62 inches (this is actually really good)<\/li>\n
- Speer 135gr. Gold Dot Short Barrel +P: 13.5 inches of penetration, expanded to .44 inches<\/li>\n
- Winchester 130gr. PDX1 Defender +P: 12 inches of penetration, expanded to .63 inches<\/li>\n<\/ul>\n
A note on all those numbers: none of those loads are pleasant to shoot out of a small gun, and in the hands of a new shooter can actually cause serious accuracy issues.<\/p>\n
.380 ACP Ballistics<\/h3>\n
![\"federal](\"https:\/\/www.targetbarn.com\/broad-side\/media\/380ballistics.jpg\" "\\".380")
Three rounds of Federal .380 90gr. Hyrda Shok in ballistic gel.<\/figcaption><\/figure>\n But how did the .380 ACP ammo<\/a> perform?<\/p>\n
- \n
- Federal 90gr. Hydra Shok<\/a>: 25 inches of penetration, no expansion<\/li>\n
- Hornady 90gr. FTX Critical Defense<\/a>: 13 inches of penetration, expanded to .52 inches<\/li>\n
- Remington 102gr. Ultimate Defense: 16 inches of penetration, expanded to .40 inches<\/li>\n
- Speer 90gr. Gold Dot<\/a>: 11 inches of penetration, expanded to .49 inches<\/li>\n
- Winchester 95gr. PDX1<\/a>: 9.5 inches of penetration, expanded to .63 inches<\/li>\n<\/ul>\n
So, What’s Better?<\/h3>\n
If we based our choice strictly off the numbers, the 38 Special is the clear winner here offering acceptable penetration and some expansion.<\/p>\n
The .380 ACP seems to under-penetrate when it does expand, and when it doesn’t expand it zips through people like a laser beam. But remember that those .38 Special rounds that deliver good penetration and some expansion are also going to punish the shooter. It takes a special person to want to fire more than a cylinder full of +P Golden Sabers through a Ruger LCR, and yet that is exactly what’s required to get good enough with the gun to put those bullets where they need to go. Plus, the .38 Special rounds might not hit to the sights, because a lot of modern snub-nosed revolvers still have fixed sights that are regulated for 158 grain lead round nose bullets.<\/p>\n
.380 vs. .38 Special Ammo Choice<\/h3>\n
![\"a](\"https:\/\/www.targetbarn.com\/broad-side\/media\/wadcutter-1.jpg\" "\\".38")
<\/p>\nWhat if I told you there was a third way, and a way for me that makes the 38 Special the clear winner here? It’s something we’ve talked about before: 148 grain full wadcutters. Most fixed sight small revolvers will shoot these rounds to the sights, they have minimal recoil, and give adequate penetration. No, they don’t expand but most critically they’re easy to shoot, and hits stop fights.<\/p>\n
The .380 ACP doesn’t have an equivalent to the full wadcutter, leaving shooters with the choice of punishing JHP that under-penetrate or FMJ that legitimately risk over-penetration.<\/p>\n
The Winner: .38 Special<\/h2>\n
![\".38](\"https:\/\/www.targetbarn.com\/broad-side\/media\/38specialammo.jpg\" "\\".38")
<\/p>\nOn the surface, the .38 Special and .380 ACP seem to be very similar rounds. But the .38 Special has an advantage in bullet selection and terminal performance. While the .380 is certainly a capable round, it just can’t close the gap. For me, and for many others, the .38 Special remains my go-to for ultra-concealable personal defense.<\/p>\n
