Buying a Used Gun: Private-Sale Inspection Checklist

🖨 Printable inspection checklist

Last updated: October 2026

Not legal advice or gunsmithing advice. This is a general checklist. If you aren't sure a gun is safe, have a qualified gunsmith inspect it before you shoot it.

Quick summary: A used gun can be a great value, but only if you check it before you pay. Meet somewhere safe, confirm it's unloaded, check the serial number, look over the outside, bore and action, and walk away if anything feels wrong. If you're new to guns, bring a friend who knows them, or meet at a gun shop where staff can take a look.

Is buying a used gun worth it?

Often, yes. Many guns are fired very little before they're sold, and a used gun can cost noticeably less than new. Some older models aren't made anymore, so used is the only option.

The trade-off is risk. A used gun may have hidden wear, damage or missing parts, and private sales are usually "as is" with no warranty. That's why an inspection matters.

Before you meet

  1. Research the model. Know the common problems and what parts it should come with (magazines, case, manual).
  2. Check the price. See How to Price a Used Gun.
  3. Ask for photos of both sides, the serial number, the muzzle, and the action open.
  4. Run the serial. Utah's free Gun Serial and CFP Search is anonymous. See How to Check if a Gun Is Stolen.
  5. Pick a safe place. A gun shop, FFL, or police station lobby. Many shops are happy to host if you're doing the transfer there. Find an FFL near you.

What to bring

  • Your ID
  • A small flashlight
  • A bore light or white card (to reflect light into the barrel)
  • Snap caps or dummy rounds, if the seller and location allow function checks [optional]
  • A printed bill of sale

The used gun inspection checklist

1. Safety first

  • ☐ Ask the seller to show the gun is unloaded, then check it yourself: remove the magazine, lock the action open, look and feel the chamber.
  • ☐ Keep the muzzle pointed in a safe direction the whole time.
  • ☐ Never bring ammunition into the inspection.

2. Serial number and markings

  • ☐ Serial number is present, clear, and matches what you checked online.
  • ☐ No signs of grinding, filing or re-stamping near the serial. If it looks altered, stop. Possessing a gun with an altered serial is a federal crime (18 U.S.C. 922(k)).
  • ☐ Make, model and caliber markings match the listing.

3. Outside condition

  • ☐ Look for cracks in the frame, slide, receiver or stock.
  • ☐ Look for rust, pitting or heavy wear, especially near the muzzle and on the slide rails.
  • ☐ Check screws for stripped heads, a sign of amateur work.
  • ☐ Check that sights are straight and secure.

4. Barrel and bore

  • ☐ Shine a light down the bore. Rifling should be crisp, not worn smooth.
  • ☐ Look for rust, pitting, or a bulge or ring (a sign of an obstruction that was fired through). A bulged barrel is unsafe.
  • ☐ Check the muzzle crown for dings.

5. Action and moving parts

  • ☐ Slide, bolt, pump or cylinder moves smoothly without grinding.
  • ☐ Safety engages and disengages cleanly.
  • ☐ Magazine inserts, locks and drops free.
  • ☐ Revolvers: cylinder locks up tight in each position and lines up with the barrel.
  • ☐ Dry-fire only with the seller's OK and snap caps where the manufacturer recommends them.

6. Parts and paperwork

  • ☐ Number of magazines matches the listing.
  • ☐ Original box, manual, or receipts, if promised.
  • ☐ Any aftermarket parts are disclosed. Ask if anything was modified or repaired.

7. Ask the seller

  • How long have you owned it?
  • How many rounds, roughly, has it fired?
  • Any malfunctions, repairs, or modifications?
  • Why are you selling it?

Vague or changing answers are a warning sign.

Red flags: walk away if…

  • The serial number is missing, scratched or doesn't match.
  • The seller won't let you look closely or rushes you.
  • The bore is badly pitted or bulged, or the frame is cracked.
  • The price is far below market with no good reason.
  • The seller won't meet at a shop or public place.
  • The seller wants payment before you see the gun. See How to Avoid Gun Classifieds Scams.

After the inspection

  1. Agree on the final price. If you found problems, it's fair to renegotiate.
  2. Complete the transfer legally. For Utah-to-Utah sales, you can buy in person or at an FFL. Out-of-state sales must go through an FFL in the buyer's state. See How to Sell a Gun Privately in Utah and FFL Transfers Explained.
  3. Sign a bill of sale.
  4. Transport it safely. Unloaded and cased. In Utah, carrying a loaded rifle or shotgun in a vehicle is a misdemeanor unless you have a concealed carry permit (Utah Code 76-11-204).
  5. Get it checked if unsure. A gunsmith inspection before you shoot is cheap peace of mind.
