What Should I Look for When Buying a Used Gun? A Buyer’s Guide
Quick Answer
When buying a used gun, your primary focus should be ensuring the firearm is safe, functional, and legally compliant for your specific needs. Unlike a new firearm, a used piece may have signs of wear that affect its mechanical timing or structural integrity. To make a smart purchase, evaluate the following factors:
- Mechanical Function: Test the action, trigger pull, and safety mechanisms. Ensure the trigger is crisp and the safety engages and disengages properly.
- Bore and Rifling: Inspect the barrel for pitting, rust, or excessive wear. Use a bore scope to check if the rifling is still sharp and distinct.
- Condition: Look for ‘holster wear’ on the finish, which indicates use, but watch more closely for cracks in the frame or slide.
- Magazine Integrity: Check that magazines lock securely and that the follower springs haven’t suffered from metal fatigue.
- Legal Compliance: Ensure the firearm is legal in your state and that the transfer is handled through a licensed FFL.
Buying used is a cost-effective way to acquire a high-quality firearm like a classic 1911 or a modern striker-fired pistol without paying MSRP, provided you perform a thorough inspection.
The Mechanical Inspection
The most critical step in evaluating a used firearm is the mechanical check. Start by visually verifying the weapon is empty. Once confirmed safe, cycle the slide or bolt to ensure it moves smoothly without binding or excessive grinding. Pay close attention to the trigger group; a used gun should still have a consistent, predictable break. If the trigger feels ‘mushy’ or fails to reset, the internal components may be worn or require expensive repair.
Furthermore, always test the safety mechanisms. On modern semi-automatic pistols, ensure the manual safety or decocker functions exactly as intended. For revolvers, check the cylinder rotation for smoothness and ensure the extractor- tip does not show signs of being chipped or bent.

Evaluating the Barrel and Rifling
The condition of the bore determines how much life the firearm has left. Use a flashlight to look through the chamber. You are looking for pitting—small craters of corrosion caused by moisture or poor storage. Pitting can significantly degrade accuracy. You should also inspect the rifling, which are the spiral grooves that spin the bullet. If the grooves appear smooth or ‘blown out,’ the barrel may be nearing the end of its life and will require replacement.
For serious buyers, using a digital bore scope is a wise investment. It allows you to see deep scratches or obstructions that might be invisible to the naked eye. If the barrel is clean and the rifling is sharp, the firearm is likely capable of maintaining the performance standards set by SAAMI for industry-standard ammunition pressure and chamber safety.
Visual Wear vs. Structural Damage
The appearance of a gun tells its story. Minor finish wear—thinning of the blue on the edges of the slide—often suggests the gun was carried regularly, which can actually be a sign of a well-maintained tool. However, you must watch for structural damage. Look for cracks in polymer frames, especially around the stress points where the rails meet. In metal frames, check for any dents or warping that could indicate the gun was dropped from a significant height.
Always check the magazines. Magazines are often the most neglected part of a used firearm. Look for bent followers or weakened springs that could cause feed failures. If you find a great firearm but the magazines are suspect, you can always find quality ammunition and replacement parts to ensure you have reliable rounds for defense or range.
Legal Transfers and Safety Protocols
Regardless of the gun’s condition, the transaction must be legal. In many states, private sales must be facilitated through a Federal Firearms Licensee (FFL) holder to perform a background check. It is your responsibility to stay informed on local laws to ensure your purchase is in full compliance. You can stay updated on the latest 2nd Amendment news to understand how your rights are evolving across state.
Once you have verified the firearm, always perform a ‘function test’ with snap caps (dummy rounds) to ensure the extractor and ejector are working correctly. At BT Gun Company, we believe every gun owner has the right to protect themselves with safe, reliable equipment.
