Shooters in the United States have often noticed that the label on the Glock pistol case comes in different colors. Why? Well, with everything Glock, there’s a reason. Let’s dive into the meaning of the various colors.
It should be noted that the various colors discussed here really only started when Glock went to the clam-shell style cases. This occurred after the beginning of the Gen 3 pistol production. Early Gen 3 pistols still came in the old Tupperware style cases that were updated to fit pistols with finger grooves.
There are at least seven pistol case label colors used on Glocks seen in the U.S.:
White: Low capacity magazines (mags do not exceed 10 rounds). This was to comply with states with magazine capacity limitations. This includes (at one time or another):
California, Colorado, Connecticut, District of Columbia, Hawaii, Maryland, Massachusetts, New Jersey, New York, and Vermont. White label pistols are often now referred to as “California compliant” pistols.
Red: High capacity magazines (high capacity mags hold 10+ rounds)
Blue: High capacity magazines. The buyer must meet blue label requirements to be eligible (see https://us.glock.com/en/buy/blue-label-program). Under the right circumstances, ANYBODY can buy them unless they are in a state with magazine capacity restrictions. Can also be govt/mil contract guns.
Purple: Contract overrun guns. Can be sold to anyone, and are not required to meet MAP pricing. Could be just overseas/export contract overruns. These also don’t usually show the quantity or capacity of the magazines on the label in the normal middle-lower space. And they often don’t show the type of sites or trigger weight in the upper-middle space.
Orange: Factory rebuilt guns. Can be sold to anyone, and are not required to meet MAP pricing
Green: U.S. manufactured for export. These also don’t usually show the quantity or capacity of the magazines on the label in the normal middle-lower space.
Yellow: Rebuilt (in two cases I’ve seen, Gen 4 MOS, and cutaway). I’ve heard that yellow labels are just faded orange labels, or just maybe a different supplier of labels for the rebuilt guns. That’s certainly plausible.
For Gen 3, white and red label come with 2 magazines, blue label come with 3.
For Gen 4 and later, all guns regardless of label color come with 3 magazines. An exception to this is the slimlines, which come with two magazines.
I’ve written before about how the SKU number in the upper right is broken down to signify the details of the pistol. See that info at Product SKU Number Breakdown.
Here is a breakdown of the product/SKU numbers found in the upper right corner of the case label. These only appear on pistol cases seen in the U.S., regardless of where they were manufactured. Label formats are different outside the U.S. There are plenty of deviations from this list from Glock, which should be no big surprise. I’ve documented over 500 625 different SKUs just since Glock went to this format with the Gen 3 guns. Note that this is constantly evolving, and I’ve even seen some new info pop up just since the 43X and 48 were announced. If you have a label that has characters other than what is listed here, let me know. I’d love to see a case label and info so I can investigate.
Note that it’s common to see SKUs listed that start with ‘GL’. The best I’ve been able to determine is that is a prefix that distributors like Lipseys add for internal use. The ‘GL’ is not part of the true Glock SKU number. Below each SKU is a UPC code that correlates to the SKU.
In the sections below, I break down the various characters, using the example SKU of PI2350202T. The bold items are the ones that are most common.
Prefix 1 – PI2350202T
E = US manufactured for export (green label)
F = Federal agency – non-military (red label on the ones I’ve seen)
G = Rebuilds FET IN (orange label)

Known anomalies are:
The U.S. manufactured Gen 4 17T, with a SKU of PG1050202, which would indicate Austrian manufacture.

UPDATE: By the way – I wrote a quick Excel calculator to break down an entered product SKU. Just enter your SKU in the colored field and hit ENTER. The spreadsheet does use macros, but only for the functionality of the buttons. Download it here.
NOTE: This spreadsheet doesn’t take into account some of the anomalies or recent changes listed above.
Different Style Labels Outside of America
For pistols made outside of the U.S. that are not destined for the States, Glock uses an entirely different label format and SKU. The SKU number appears to just be a 4 or 5 digit number.
This is a running list of things I’m actively looking for. This is a living post and will be updated as needed. If you have any of these items and are looking to part with them, or know where I can obtain them, please contact me. All firearms transactions MUST go through an FFL.
Note: Items that are strike-through are items I’ve purchased but have not yet received.
These are publicly released pistols that I’m actively looking for. Many are fairly hard to find. I prefer those pistols with original case, including matching case label, and all case contents (loader, brush, rod, lock, correct manual/packet, spent casing, etc.). But I’m willing to discuss any opportunity.
