In Starfield, you can buy ammo from weapon shops, general stores, and Trade Authority kiosks in most major hubs, with New Atlantis, Neon, and Akila City being the most reliable places to stock up.

Best Places to Buy Ammo (Quick Scoop)

New Atlantis (Jemison)

New Atlantis is the easiest and most consistent answer to “starfield where to buy ammo.”

Key spots:

  • Jemison Mercantile – Often considered the best early-game ammo vendor, right by the security bay when you enter the city.
  • Centaurion/Centurion Arsenal – In the Residential District; sells most ammo types and is great once you start using higher-tier weapons.
  • UC Distribution Center – In the Commercial District; mainly resources, but also ammo, grenades, spacesuits, and weapons.
  • UC Surplus & Apex Electronics (The Well) – Smaller vendors that also carry ammo and some weapons.

These few shops are enough to keep an early–mid-game character supplied if you rotate through them regularly.

Neon (Volii Alpha)

Neon is another ammo-rich city, especially useful once you start chasing more specialized loads.

Main vendors:

  • Neon Tactical (Neon Core) – Dedicated weapons shop; very good general ammo selection.
  • Kore Kinetics (Trade Tower, Neon Core) – Specializes in ballistic weapons using MI-type ammo; widely recommended as the best place to get .43 MI ammo (for guns like the Keelhauler).
  • Arboron (Ryujin lobby) – Focused on LZR (laser) ammo only.
  • Frankie’s Grab and Go (Ebbside) – Convenience-style shop that also stocks some ammo.

If you’re low on advanced ballistic ammo like .43 MI, Kore Kinetics in Neon is often the go-to stop.

Akila City (Akila)

Akila City is a strong choice if you’re running more traditional firearms.

Key shops:

  • Rowland Arms – Pure gun shop on Main Street; sells lots of ammo but only buys guns from you.
  • Shepard’s General Store – On the main path from the spaceport; sells guns, gear, and ammo, and is convenient for quick restocks.
  • Laredo Firearms – Another dedicated weapons vendor in the city.

If you like running one or two favorite calibers, Akila’s cluster of weapon shops makes topping off quick and efficient.

Other Notable Ammo Vendors

Outside the “big three” hubs, there are plenty of smaller shops that can help when you’re traveling.

Some reliable names:

  • The Key – Has a Weapons Shop and Zuri’s Essentials that sell ammo, provided you haven’t locked the area by siding with UC at the end of the Crimson Fleet questline.
  • Gagarin Landing (Gagarin) – Clint’s Collectibles sells weapons and ammo.
  • Hopetown (Polvo) – Best Defense is a strong general combat outfitter with ammo.
  • Paradiso (Porrima II) – General Store with ammo and general supplies.
  • New Homestead (Titan, Saturn’s moon) – New Homestead Store carries basic ammo and gear.
  • Cydonia (Mars) – Jane’s Goods and the UC Exchange both sell ammo.
  • Red Mile (Porrima III) – Sati Chandra acts as a vendor with ammo on top of other goods.

On top of that, nearly every major settlement has at least one Trade Authority vendor, and these usually sell a mix of ammo types as well.

How Shop Ammo Works (And Why It Feels Random)

Ammo inventories in Starfield are partially randomized, so you won’t always see the same calibers each time you visit a vendor.

You might find a specific ammo type (like .43 MI) at Rowland Arms once and then not see it again on your next visit, even though the store still sells that category of ammo.

Because of this:

  • Rotate between several weapon shops in one hub (e.g., Jemison Mercantile + Centaurion Arsenal + UC Distribution Center in New Atlantis).
  • Use multiple cities for rare ammo types, such as Kore Kinetics in Neon plus Rowland Arms in Akila for MI ammo.

Refreshing Shop Ammo

If you want to “stack up” on ammo from a favorite vendor, you can refresh their inventory using the wait mechanic.

Basic method:

  1. Buy all the ammo you want from the vendor.
  1. Find a nearby chair or bed in the same area.
  1. Sit or lie down and use the Wait option for 24 in‑game hours.
  1. Stand up, talk to the vendor again, and check the ammo tab; their stock will have reset and can include the same rare ammo you just bought.

Players often repeat this loop several times to build up big stockpiles of rare shells like 7.5mm or 40mm.

Extra Tips for Not Running Dry

  • Loot every fight : Enemies often drop ammo matching their weapons, which helps offset how “limited” ammo can feel.
  • Diversify weapon types : Swapping between guns that use different calibers makes it less likely you run a single ammo pool to zero.
  • Use powerful weapons sparingly : High-damage niche guns (like some MI-based pistols) can be treated as “boss” or “elite” killers since their ammo is harder to replace.

TL;DR:
If you just want one answer for “starfield where to buy ammo,” head to Jemison Mercantile and Centaurion Arsenal in New Atlantis , or Neon Tactical and Kore Kinetics in Neon , buy everything you need, then wait 24 hours nearby to refresh their stock and repeat.
