How Much Is an FN FNX-45 Worth? (2026 Update)

How We Calculate Used FN FNX-45 Values

The price of an FN FNX-45 is affected by its condition, the model or variant, and its accessories or upgrades.

Condition and Value

If you’re selling an FN FNX-45, you’ll get more for it if it’s in better condition. For preowned guns, the condition is typically graded by a firearm expert in an appraisal.

Gun appraisal often has a fee, but we do it for free as part of our offer process. Just submit your gun here to get an appraisal and offer.

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

Anyway, here are the usual condition tiers:

Like-New or Mint

• For preowned guns, worth the most
• Never actually used
• Perfect form and function

Excellent

• About 10% less than mint
• Only lightly used, almost invisible wear
• Near-perfect form, perfect function

Very good

• About 20% less than mint
• Used occasionally, with mild wear
• No major aesthetic issues, perfect function

Good

• About 30% less than mint
• Used often but cared for properly
• Worn but not unattractive, perfect function

Fair

• About 40% less than mint
• Used often and not cared for properly
• Wear is unattractive, mostly intact function

Poor

• About 50% less than mint
• Beat up, scratched, dented, or rusted
• May not even work

How We Appraise FN FNX-45 Models

There are two main submodels for the FNX-45. They vary slightly in value, whether in retail or resale.

FN FNX-45 Value

The average used FN FNX-45 is worth $315 to $650. A new FN FNX-45 costs $850 at retail.

The FNX-45 comes in 10-round and 15-round options as well as Black and FDE finishes. A stainless steel slide is paired with a polymer frame, interchangeable backstraps, and double-action/single-action design.

FN FNX45T or FNX-45 Tactical Value

The average used FN FNX-45 Tactical is worth $440 to $950. A new FN FNX45T costs $1,200 at retail.

The FN FNX-45 Tactical adds an optics-ready slide, suppressor-height night sights, and threaded barrel to the package.

This makes the Tactical version the model of choice for those who want easy addition of accessories. It’s also why you can often sell an FNX-45 Tactical for more than the basic model.

This is a model that holds value well. Because it’s a premium firearm in the line, we use a secure gun shipping and buying system to ensure every transaction is fully insured and legally compliant.

How Accessories Affect What We Pay for Your FNX-45

There are a few accessories or upgrades you can bundle with an FNX-45 to boost its resale value. This is always up to the buyer, however. Some buyers simply won’t buy accessories and only want the gun.

If you can’t find takers for your firearm accessories, contact us. We regularly buy everything gun sellers have to offer, from the accessories to the ammo.

Original Box, Bag, and Papers

The FNX-45 comes with an FN-embroidered cloth carrying case (or tactical bag) inside its cardboard packaging. If you have this in good condition, you can sell your FNX45 with it and the papers for added value and proof of its originality.

Note that the older tactical bags usually cost more if in great quality. It’s because they had more slots and pouches than the smaller new ones.

Value: Around $15 to $30 for the matching box and papers.

Pistol Sights

Good sights don’t just add to the gun’s accuracy – they can also add a lot to its style. If you have something good like a Vortex or Holosun, try selling it with the gun.

Value: Add 30% to 50% of the accessory’s  original value.

Suppressors/Silencers

Good suppressors can keep a lot of their value, especially quality ones like the Obsidian 45 ($900 at retail). Since most people interested in FNX45 pistols want to run it with silencers, you can often add this to your package.

Value: Add 30% to 50% of the accessory’s  original value.

Compensators

Pretty good for reducing muzzle rise. Popular options like the Apex MRAT ($175 at retail) are usually in demand.

Value: Add 25% to 45% of the accessory’s  original value.
