Best .380 ACP Defense Ammo
The penetration problem with .380 — and the loads that actually reach vital depth from pocket pistols.
The Bottom Line
The .380 ACP presents a real ammo dilemma: from short pocket-pistol barrels, many hollow points either expand and fail to penetrate deep enough, or penetrate well but don't expand. Testing has shown that some shooters are better served by a quality FMJ in .380 to guarantee penetration depth, while others choose a proven JHP designed specifically for the round, such as Hornady Critical Defense or the heavier-for-caliber loads engineered for low-velocity reliability.
The practical approach: pick a defensive load with a track record of adequate penetration from short barrels (Hornady Critical Defense and Federal HST Micro are common recommendations), then verify it feeds 100% in your specific pocket pistol. Because .380 is already at the margin, reliability and penetration matter more than chasing maximum expansion. Confirm your choice with a couple of boxes before you carry it.
