The fastest way to lose money on a gun is to guess its value. Price too high and it sits for months; price too low and it sells in an hour to someone who knew better. The good news is that firearm values are easier to research than most used goods, because the same models trade hands constantly. Here is the process experienced sellers and dealers use.
Step 1: Identify exactly what you have
“A Smith & Wesson revolver” could be worth $300 or $3,000. Before you research anything, write down:
- Manufacturer and exact model (and generation, variant or dash number — a Glock 19 Gen 3 and Gen 5 are priced differently; an S&W Model 19-3 differs from a 19-5).
- Caliber and barrel length.
- Finish (blued, stainless, nickel, Cerakote) and any factory special edition or distributor exclusive.
- Approximate year of manufacture, which you can often work out from the serial number using the manufacturer’s customer service line or published serial-number tables.
- What comes with it: original box, manual, extra magazines, factory paperwork, sights, optics.
Step 2: Grade the condition honestly
Condition drives value more than anything except the model itself. Most of the industry uses some version of the NRA condition standards or a “percent of original finish” scale. A practical version for modern guns:
- New / unfired — never shot, in the original box with everything it shipped with.
- Like new / excellent — fired very little, no visible wear beyond a faint turn line or holster mark.
- Very good — light, honest wear on edges and high points; mechanically perfect.
- Good — obvious finish wear, small scratches or dings, works correctly.
- Fair — heavy wear, possible rust spots or replaced parts, still safe and functional.
- Poor / parts — damaged, non-functional or needs a gunsmith.
Look at the bore with a light, check the muzzle crown for dings, and note any pitting, cracks in grips or stocks, or aftermarket parts. Buyers will find these things; finding them first lets you price accordingly. Our used gun inspection checklist walks through the same checks a careful buyer will make.
Step 3: Find what it actually sold for — not what people are asking
Asking prices tell you what sellers hope for. Sold prices tell you what the market will pay. Good sources:
- Completed online auctions. Ended auctions with bids are the best real-world data for used guns. Look at several sales of the same model in similar condition and throw out the highs and lows.
- Current new retail price. For models still in production, a used gun in excellent condition typically sells for meaningfully less than new — buyers expect a discount for giving up a warranty and a fresh box. If yours is priced near new, it needs a reason (discontinued, rare finish, extras).
- Printed and online value guides such as the Blue Book of Gun Values. These are useful for older and collectible guns and for understanding condition premiums, but they lag the market for popular modern models.
- Local dealers. Ask what a shop would sell your model for. Their offer to buy it will be lower, because they need room for profit — that’s normal, and it gives you a floor.
What adds value
- Original box, papers, manual and all factory accessories (especially on collectible and discontinued models).
- Discontinued models, limited runs and desirable variants.
- Quality optics, sights or factory upgrades — though buyers rarely pay full price for add-ons. Consider selling expensive optics separately.
- Documented provenance on historic and military surplus firearms.
- High original finish on older guns. On collectibles, the difference between 90% and 98% finish can be large.
What lowers value
- Refinishing or re-bluing a collectible — it often cuts collector value sharply even when it looks better.
- Pitting, rust, a worn bore or a damaged crown.
- Aftermarket modifications that narrow your buyer pool (unusual triggers, cut stocks, custom engraving).
- Missing magazines or parts that are hard to find.
- Calibers that are expensive or hard to find ammunition for.
Pricing strategy: fixed price or auction?
Fixed price works well for common models with a clear market value. Price at or slightly below recent sold prices for a quick sale, or a little above if you’re willing to wait and accept offers.
Auctions work well for collectible, rare or hard-to-value guns, where competition can push the price above what you’d dare ask. Protect yourself with a reserve price at the lowest amount you’d accept, and consider a Buy Now price for a buyer who doesn’t want to wait. A low opening bid attracts watchers; the reserve keeps you from selling too cheap.
Don’t forget the costs
When you compare a private sale with selling to a dealer, account for what you’ll spend: shipping to the buyer’s FFL (firearms have carrier restrictions — see how to ship a gun), payment or escrow fees, and your time answering questions. Buyers also pay an FFL transfer fee on their end, which they’ll factor into what they offer you.
Quick checklist
- Identify the exact model, variant, caliber and year.
- Grade condition honestly and photograph any wear.
- Find at least five recent sold prices for the same model and condition.
- Adjust for extras, box and papers, and anything that lowers value.
- Choose fixed price (common guns) or auction with a reserve (collectible or hard-to-value guns).
- List with clear photos and an honest description — see how to sell a gun online legally.
