Sierra 380 Auto 90gr JHP Outdoor Master Ammo – 20 ct Box

Sierra 380 Auto JHP gives pocket pistol owners a defensive load from a serious bullet maker, packed 20 rounds to a box in the Outdoor Master line. The bullet is a 90 grain jacketed hollow point in 380 Auto. Small guns deserve good ammunition, and this is a box built with that in mind.

Why Sierra 380 Auto JHP Matters in a Small Gun

.380 ACP asks more of a hollow point than any of the larger service cartridges do. Velocity is modest, barrels are short, and bullet weight is limited by the size of the case. Designing a projectile that performs under those constraints is genuinely difficult, which is why bullet design experience counts here.

This is for the shooter carrying a pocket .380 for daily defense, the person who keeps one in a bag or a drawer, and anyone who has decided that the gun they will actually carry beats the gun they leave at home. That is a completely reasonable decision, and it deserves proper ammunition.

Key Features

• 90 grain jacketed hollow point, the standard defensive weight for the caliber
• Outdoor Master line, developed for defensive and outdoor carry use
• Twenty rounds per box, the usual count for a defensive load
• Clean ignition and consistent velocities that build trust in your zero
• Feeds smoothly through the tight feed ramps found on small .380 pistols
• Sierra bullet construction from a company built on projectile making

Specifications, Explained Plainly

The caliber is .380 Auto, also marked .380 ACP or 9mm Short depending on the pistol. It is a lower pressure cartridge than 9mm Luger, which is exactly why the guns chambered for it can be built small enough to disappear in a pocket.

At 90 grains the bullet sits at the light end of what the caliber loads, and light bullets carry more velocity. In a cartridge where velocity is the limiting factor for hollow point performance, that choice is deliberate rather than incidental.

Twenty rounds is enough to load your carry magazines and keep spares. Buy two boxes if you want to run a full function test and still carry fresh ammunition, which is the approach we recommend for any small pistol.

Sierra 380 Auto JHP is also a sensible choice for a shooter who owns more than one .380, since a single load tested across both guns keeps your inventory simple. Small pistols vary more than full size guns do, so confirm each one individually.

Reliability, Testing and Storage

Function testing matters more with a small pistol than with a full size gun. Short slides, stiff recoil springs and tiny feed ramps leave less margin, so run rounds through the gun from magazines and confirm it cycles cleanly before you rely on it.

Check your magazine springs while you are at it. A worn spring in a pocket pistol causes more feeding trouble than the ammunition ever will, and magazines are cheap compared to the consequence of one that does not do its job. Replace anything that looks tired rather than nursing it along.

Keep the box cool and dry, and stock up on inexpensive full metal jacket practice rounds from our ammunition range so you can put real trigger time into a gun that most people badly under practice with.

Good Ammunition for a Small Package

A pocket .380 is a compromise gun, and compromises deserve the best components you can put in them. Ammunition is the cheapest upgrade you will ever make to a defensive handgun.

Test it, carry it, and practice with the gun far more than most owners do. Sierra knows what goes into a bullet, and Sierra 380 Auto JHP reflects that experience. This ammunition ships straight to your door wherever state and local law allows.
