What Affects the Value of a Glock 40?
Glock 40 value is affected by the gun’s condition and its accessories or upgrades.
Model doesn’t affect its value much for a simple reason: there’s only one G40 model. That’s the Gen 4 Glock 40 MOS introduced in 2015 at SHOT Show.
Value Factor 1: Condition

New guns sold at retail are usually worth the most. For second-hand guns, the best-condition ones take pole position.
To find your preowned gun’s condition, you should have it appraised by an expert. This may cost money. However, we offer gun appraisal for free online to gun sellers.
Once you know the condition of your gun, you can use this key to answer “How much is my Glock 40 worth.”

Value Factor 2: Accessories or Upgrades

It’s fairly common to find the Glock 40 being resold with accessories since its main variant is an MOS one. MOS Glocks are designed to make adding upgrades like optics easier.
That being said, it’s important to remember that not all buyers will want to buy the upgrades along with your gun. Some will only be interested in paying for the gun itself.
If you’re having trouble selling a G40 with accessories, approach us. We often make offers for accessories – and even ammo!
Original Box and Papers
Who doesn’t appreciate the classic Glock tupperware boxes? If yours isn’t beat up, offer it with your gun.
Value: Around $10 to $20 for the matching box and papers.
Spare Magazines
Spare magazines are among the most popular upgrades or add-ons to gun packages. Add yours to the gun you’re selling to boost the value.
Value: Around $5 to $10 a mag.
Optics or Sights
If you have a good optic or sight to go with your G40, add it to the bundle. Stuff from Trijicon and Holosun tends to sell fastest. Just remember that if it’s in poor condition, you’ll take a haircut.
Value: Around 30% to 50% of the optic’s original value.
Weaponlight
It’s pretty common to see people sell G40 pistols with a weaponlight attached. Try adding yours if you have a decent one, like the TRLs from Streamlight.
Value: Around 20% to 40% of the weaponlight’s original value.
