Probably Stolen - Cyberpunk Shopkeeper Sim: Gunsmithing Is Way Too RNG to Get the Right Chips for Proper…

What you need to know

Gunsmithing in Probably Stolen becomes extremely RNG‑heavy once you move past the cheap plastic weapons. To craft Class 2 or 3 guns you must first acquire a set of specific chips and modules for each printer, and the cost of those modules can exceed 800 credits per printer. Without the right chips you’ll be stuck making only basic pistols, and the money you earn from low‑level jobs dries up quickly.

Step by step

1. Secure a 3D printer chip that allows you to craft gun parts – This is the only chip that unlocks the ability to produce your own frames and gun parts. It is sold by a merchant, so you’ll need to keep checking vendor inventories until it appears.

2. Obtain the Metal Printing chip – Required for any metal‑based weapon. Like the gun‑part chip, it is sold randomly by merchants.

3. Buy the Computer Numerical Control (CNC) modules – Each printer needs a CNC module before it can handle metal work. These also come from merchants and are priced around 800 credits per printer.

4. Collect the Frame chip – This chip lets you combine a weapon frame with a gun part. It is notoriously rare; you may need to rely on luck or trade with other players.

5. Gather the Gun‑part chip – Similar rarity to the Frame chip; without it you cannot finish a metal gun.

6. Set up a printer for each class – Once you have the Metal Printing chip, CNC module, Frame chip, and Gun‑part chip for a printer, you can start producing Class 2 or 3 weapons.

7. Use Dr. Jackson’s “Black Lamp” service – If you have spare customer slots, assign them to “Petty Thief”. This can occasionally yield the missing chips you need, though it’s still chance‑based.

8. Repeat the merchant‑checking loop – Keep revisiting all merchants daily. The chips and modules appear randomly, so persistence is key.

9. Manage your cash flow – While you’re gathering chips, focus on low‑cost jobs that still generate credits. Avoid spending on unnecessary upgrades until you have the full printer setup.

10. Craft the desired weapon – With all required chips installed, select the appropriate frame and gun part in the printer menu to produce the final metal gun (e.g., a space shotgun or higher‑tier pistol).

Tips

• Prioritize the gun‑part chip and frame chip – Without both you cannot finish any metal weapon, no matter how many other modules you have.
• Keep an eye on the merchant’s rotating stock – The chips appear infrequently, so checking every few hours maximizes your chances.
• Use “Petty Thief” slots sparingly – They can provide a rare chip, but they also occupy customer slots that could bring in income.
• Don’t upgrade to Class 2 too early – The module cost can cripple your cash flow; make sure you have a steady stream of low‑level jobs before committing.
• Save credits for the CNC modules – Each printer needs its own module, and they are the biggest single expense.
• Accept the RNG – Even with optimal play, the system is designed to be random; plan for long downtimes between successful chip drops.
