Current Market Value of a Sig Sauer MPX
How much is a SIG Sauer MPX worth today? The average used SIG Sauer MPX is worth $700 to $1,700, but it varies by model. A new SIG MPX SBR sells for $2,000 at retail.
What Affects the Value of a SIG Sauer MPX?
SIG Sauer MPX value is affected by its condition, model, and accessories or upgrades.
Value Factor 1: Condition
For a preowned SIG Sauer MPX to hit maximum value, it generally needs to be in great condition. Wear brings down a gun’s value.
You can have a firearm expert or appraiser inspect your gun to assign it a condition score. This often costs money. However, we offer free gun appraisal online if you’re selling to us.
Through that, you can find the answer to “How much is my SIG Sauer MPX worth” using the key below.

Value Factor 2: SIG MPX Models or Variants
SIG has made several versions of the MPX over the years. Here are some of the ones we see in resale.
SIG Sauer MPX 8” Value
The average used SIG Sauer MPX 8” is worth $700 to $1,700. A new SIG MPX 8” sells for $2,000.
The standard MPX has an 8” barrel, a collapsible stock, and 30-round capacity. It’s chambered for 9x19mm Parabellum, is select-fire, and is considered an NFA Class III item.
Note that there are complications that come with transferring Class III firearms. If you want to skip most of the hassle, consider selling your NFA item to us, as we make it simpler.
SIG Sauer MPX Pistol Value
The average used SIG Sauer MPX Pistol is worth $650 to $1,500. A new SIG MPX Pistol sells for $2,000.
This also has an 8” barrel but is a semi-automatic pistol variant typically found without a stock. Because it’s not an NFA firearm, it’s easier to sell than the select-fire version – and easier to find too.
SIG Sauer MPX-K Value
The average used SIG Sauer MPX-K is worth $750 to $1,800. A new SIG MPX-K sells for $2,100 at retail.
This is the standard compact model with a 4.5” barrel. It comes in two versions: one with a collapsible arm brace and one without (but still capable of being fitted with one).
This is one of the most popular versions of the MPX, by the way, so it sells out fairly often at shops. That tells you that you have a good chance to sell your MPX easily if it’s this one.
SIG Sauer MPX Copperhead Value
The average used SIG Sauer MPX Copperhead is worth $700 to $1,500. A new SIG MPX Copperhead sells for $2,000 at retail.
An ultra-compact version of the MPX with a monolithic coyote tan Cerakoted upper receiver (although all-black versions have been made). This one has a barrel only 3.5” long, and is chambered for 9mm Luger.
You can get this version of the gun with or without a brace, like the other pistol models.
SIG Sauer MPX PCC Value
The average used SIG Sauer MPX PCC is worth $700 to $1,800. A new SIG MPX PCC is worth $2,100.
A semi-automatic pistol-caliber carbine version with a 16” barrel. It has a Timney trigger, slim M-LOK handguard, telescoping stock, and 3-chamber compensator.
The old version (MPX-C) differs from the modern one by having a 6.5” barrel with a 9.5” muzzle device permanently welded to it.
The old version is considered a Title II NFA weapon because of a muzzle device (which the BATFE deemed to be a suppressor). The modern version, the MPX PCC, lacks that device and is thus easier to transfer.
Taran Tactical SIG Sauer MPX PCC John Wick 3 Value
The average used SIG Sauer MPX PCC is worth $1,600 to $4,000. A new TTI JW3 SIG MPX PCC is worth $4,500.
Technically, this is one of the Taran Tactical guns. Still, they do build on a SIG MPX PCC to make it, so we’ll count it here.
This heavily modified version of the MPX PCC was seen in the John Wick 3 film and comes with upgrades like the HIPERFIRE Eclipse tuned trigger, Lancer carbon fiber handguard, and Trijicon MRO. It also comes with Coyote bronze accents on the basepads, among others.

Value Factor 3: Accessories or Upgrades
Some accessories can boost the value of your preowned gun. They have to be in excellent condition, from popular manufacturers, and be appealing to the buyer, however.
This tells you that there will be times when your buyer won’t bite. Some buyers just don’t want accessories and are only interested in the gun itself.
If you’re struggling to sell your SIG MPX with its accessories, try us. We make offers for just about all firearm items, from accessories to ammo.
Original Box and Papers
The SIG Sauer MPX usually comes in a cardboard box with styrofoam inside. If yours is still pristine, you may be able to get something for it.
Value: Around $8 to $15 for the matching box and papers.
MPX PSB
The MPX PSB is the pistol-stabilizing brace you can fit onto the braceless MPX pistols (and some MCX ones, actually). If the gun you’re selling doesn’t have it attached yet, definitely try offering it as part of the kit. It often retails for $199 by itself.
Value: Around 30% to 50% of its original value.
Spare Magazines
Most people will appreciate these. SIG mags for the MPX do tend to be ridiculously expensive, though, so don’t be surprised if your buyer hesitates.
Value: Around $13 to $30 per SIG mag, less if from another manufacturer.
