What makes .380 ACP loads for pocket pistols different?
.380 ACP is a low-pressure cartridge usually fired from very short barrels, so its bullets reach the target slower than most defensive handgun rounds — and hollow-point expansion depends on impact velocity. SAAMI's maximum average pressure for .380 ACP is 21,500 psi, against 35,000 psi for 9mm, and typical pocket pistols have barrels of roughly 2.75 to 3.5 inches. A defensive .380 load therefore has to balance two things that pull against each other: expanding reliably at low velocity, and still penetrating deeply enough.
Manufacturers address that in different ways — polymer-filled cavities that resist clogging, heavier bullets for penetration, or designs tuned to expand at the velocities short barrels produce. The loads below are compared by those design choices and by the specifications each manufacturer publishes. The page does not rank them.
What are the specs of common .380 ACP defensive loads?
| Load | Weight | Construction | Published velocity |
|---|---|---|---|
| Hornady Critical Defense (90080) | 90gr | FTX: polymer-filled hollow point | 1,000 fps / 200 ft-lbs |
| Federal Personal Defense HST (P380HST1S) | 99gr | HST JHP, designed for short-barrel .380 | See Federal's product page (test barrel stated there) |
| Sig Sauer V-Crown | 90gr | Stacked hollow-point cavity JHP | See Sig's product page |
| Hornady Custom XTP | 90gr | XTP jacketed hollow point | See Hornady's product page |
| Remington Ultimate Defense | 102gr | Brass-jacketed hollow point | See Remington's product page |
Published figures for .380 loads are measured from different test barrels by different manufacturers, so velocities from two companies are not directly comparable unless the barrel lengths match. Where this table refers you to the product page, retail listings report conflicting figures and we have not reproduced one. From your own pocket pistol, expect lower velocity than a manufacturer's longer test barrel.
How do the bullet designs differ?
Polymer-filled hollow points (Hornady FTX). The polymer insert keeps fabric from packing the cavity — a known problem for hollow points at low velocity — and pushes the cavity open on impact. At 90gr, this is a lighter bullet that starts faster.
Heavier hollow points (Federal HST 99gr, Remington Ultimate Defense 102gr). A heavier bullet at lower velocity carries more momentum, which generally favors penetration depth over maximum expansion. Federal markets its .380 HST specifically for short-barrel pistols.
Conventional JHP (Sig V-Crown, Hornady XTP). Traditional hollow-point cavities without a polymer insert. Hornady's XTP is designed to favor penetration, with expansion that is more controlled than aggressive.
Each design shifts the balance between expansion and penetration. Independent gel testing, when the tester reports barrel length and clothing barriers, is the way to see where a specific load lands from a pistol like yours.
How does .380 ACP compare with 9mm?
| .380 ACP | 9mm Luger | |
|---|---|---|
| SAAMI max average pressure | 21,500 psi | 35,000 psi |
| Representative factory load | 95gr at 955 fps | 124gr at 1,150 fps |
| Muzzle energy (computed) | 192 ft-lbs | 364 ft-lbs |
| Typical pistol size | Pocket pistols, often with blowback actions | Micro-compact to full-size |
Energy is computed as weight × velocity² ÷ 450,400. On those representative loads, .380 ACP carries a little over half the muzzle energy of 9mm. Some current micro-compact 9mm pistols are close in size to .380 pocket pistols; recoil, weight and how the gun carries are the trade-offs a shooter weighs. Full comparison: 9mm vs .380 ACP.
What should you check before carrying a .380 load?
| Criterion | What to check |
|---|---|
| Penetration and expansion from a short barrel | Gel tests that state the barrel length and clothing barrier |
| Feeding in your pistol | Function-test the exact load with your magazines; small .380 pistols can be sensitive to bullet shape and overall length |
| Recoil in a light pistol | Heavier bullets add recoil momentum in pistols that can weigh well under a pound |
| +P labeling | SAAMI has no +P specification for .380 ACP; a .380 "+P" box reflects the maker's own standard — see What is +P ammo? |
| Practice match | An FMJ in the same weight for training |
| Cost per round | Current tracked prices (below) |
FMJ is also sold in .380 ACP for practice. It does not expand, and like FMJ in other calibers it is generally not used as a defensive load because of over-penetration risk; see FMJ vs hollow point.
What if a specific .380 load is unavailable?
When a particular load is not available, the attributes that make two loads comparable are bullet weight, construction type, and published test data from a similar barrel. Any replacement needs its own function test in your pistol, since small .380 pistols in particular can feed one bullet shape and not another.

How much does .380 defensive ammo cost?
Defensive .380 hollow points are priced well above .380 FMJ per round. .380 ammunition is produced in lower volume than 9mm, so the smaller cartridge is not necessarily the lower-priced one — compare the 9mm and .380 pages directly. Per-round prices move, so see the tracked pages rather than a fixed range:
Quantity for a carry pistol is usually small: enough to load the pistol and a spare magazine, and enough to confirm function and point of impact in that pistol.
