How Much is a Glock 17 Worth? (2026 Value Update)

How We Calculate Used Glock 17 Values

Preowned Glock 17 values are affected mainly by the gun’s condition, model, and upgrades or accessories.

Condition and Value

You can have a gun appraised by an industry expert to learn its condition.

Determining the exact condition of a Glock can be subjective. To see how we professionally evaluate your firearm and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

Once you know your gun’s condition, you can use these tiers to estimate how much the gun's worth:

Like-New or Mint Condition

• At the top of the preowned Glock 17 price range
• Virtually perfect and never been fired
• No signs of wear or use

Excellent Condition

• Around 10% less than mint
• Near-invisible use marks
• Very rarely used

Very Good

• Around 20% less than mint value
• Used lightly
• Mild wear or handling marks

Good

• Around 30% less than mint value
• Used regularly but with care and maintenance
• Functions perfectly

Fair

• Around 40% less than mint Glock 17 prices
• Used regularly but without care
• Worn, with possible mild functional issues

Poor

• At least 50% less than mint value
• Beat up and cosmetically questionable
• May have major functional problems

How We Appraise Glock 17 Models

Glock 17 models have gone through a lot of iterations. Let’s break them up specifically into generations first.

Glock 17 Gen 1 Value

The average used Glock 17 Gen 1 is worth $200 to $500. A Pencil Barrel Glock 17 is worth around $1,500 to $5,600.

Glock 17 Generation 1 pistols were made from 1982 to 1988. They have a “pebblestone” texture on the grip and often have a parkerized barrel.

Other common features include 2-pin design and a smooth dust cover. In the front strap, there was also a mag well relief shaped like a half-moon.

The most desirable versions are the Pencil Barrel Glock 17 pistols made in the 80’s. These are long-slide versions. Glock only did 2 runs of them, so they’re rare.

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

Glock 17 Gen 2 Value

The average used Glock 17 Gen 2 is worth $160 to $320.

The Glock 17 Generation 2 pistols were made from 1988 to 1998. Many are confused for Gen 1 guns.

The easy way to tell them apart is the grip. If the pebblestone texture wraps around the grip 360 degrees, it’s Gen 1. The Glock 17 Gen 2 pistols have side panels that don’t wrap around the gun.

The G17 Gen 2 panels have a deeper texture than Gen 1s. They also have checkered front and back straps and 5 more calibers.

Glock 17 Gen 3 Value

The average used Glock 17 Gen 3 is worth $200 to $320. A new Glock 17 Gen 3 costs $499 at retail.

Glock 17 Gen 3 pistols are still in production (mainly for California). They were introduced in 1997 and brought molded finger grooves to the G17 front strap.

These also have thumb rests at the top of the grip and accessory rails in the dust cover. Some of them are collectible and are worth more. We’ll take them up separately later.

Glock 17 Gen 4 Value

The average used Glock 17 Gen 4 is worth $200 to $320.

Generation 4 Glock 17s were made from 2008 to 2020. They added modular backstraps, redesigned internals, and the aggressive “pyramid texture” on the side panels.

These guns also have a grip thumb wrest and accessory or light rail. They’re now discontinued.

Glock 17 Gen 5 Value

The average used Glock 17 Gen 5 is worth $200 to $350. A new Glock 17 Gen 5 costs $499 at retail.

These were introduced in 2017. They include an ambidextrous slide release, flat front strap, flared magazine sides, and a marksman barrel. They still have the Gen 4 pyramid texture and accessory rail.

These are still in production.

Glock 17 Gen 5 MOS Value

The average used Glock 17 Gen 5 MOS is worth $300 to $450. A new Glock 17 Gen 5 MOS costs about $599 at retail.

MOS stands for the Modular Optic System. A Glock 17 MOS is basically a gun that’s been pretapped for optic mounting.

Glock 17 Gen 3 RTF2 Value

The average used Glock 17 Gen 3 RTF2 is worth $300 to $600.

Only a few Gen 3 guns were ever made with the RTF2 or rough-textured frame 2 grips. This was the early trial of the pattern that would later become the Glock Generation 4 pyramid texture.

Because they’re rare, used Glock 17 price averages for them tend to be higher.

Glock 17C Value

The average used Glock 17C is worth $240 to $450.

This is the compensator-cut version. It’s supposed to have lower muzzle rise, permitting faster follow-up shots. It was discontinued after Gen 4, so only Gen 3 and Gen 4 17C pistols exist.

Glock 17L Value

The average used Glock 17L is worth $350 to $750 for Gen 2 to Gen 5. Glock 17L Gen 1 guns can cost more.

These are the competition or match versions of the gun. A 17L has a longer barrel, longer slide, and lightened trigger pull, among other tweaks for enhanced performance.

The Glock 17L Gen 1 and 2 guns have the highest value because they’re most collectible. Glock 17L Gen 1 value can even reach $1,600.

Glock 17M Value

The average used Glock 17M is worth $350 to $650.

The 17M is a Gen 5 Glock that’s basically the duty version of the standard 17. It has a specially coated trigger bar and connector, but is very like the commercial one in most ways.

Because it’s so functionally similar to the standard G17, most of what you’re paying for here is the collectible value of a made-for-the-FBI gun. It also comes with the AmeriGlo FBI Contract Sights.

Glock 17T Value

The average used Glock 17T is worth $200 to $350. A new Glock 17T costs $400 at retail.

The Glock 17T is a tactical operations training pistol. Typically used with plastic bullets, it’s easily recognizable from its bright blue frame.

You’ll usually find these on the market as surplus from military or law enforcement training centers.

How Upgrades Affect What We Pay for Your G17

There are several common accessories and upgrades for these guns. While they can affect used Glock 17 9mm price ranges, it’s not guaranteed.

That’s because only great-quality ones from known manufacturers actually add value. Furthermore, some buyers really just want the gun and not the extras.

• Gen 2 Manuals and Boxes - $15 to $30 used
