Glock Serial Number Research Project

THIS IS A DATABASE OF OWNER SUPPLIED DATA. IF YOU DON'T FIND YOURS LISTED, LOOK IN YOUR PAPERWORK FOR THE LITTLE BROWN ENVELOPE CONTAINING TWO FIRED CASINGS. WHAT'S THE DATE ON THAT ENVELOPE? DON'T HAVE IT? THEN PLEASE CALL GLOCK AND ASK THEM.

Please report any broken links to me so that I can fix them. I'd also like to update some of the pics below, showing the different generations / rails / slide serrations / rtf2 / etc. .

Quick links to specific serial number ranges:
<a href="#post4622166">AA-ZZ</a>, <a href="#post4622178">AAA-AZZ</a>, <a href="#post4622186">BAA-BZZ</a>, <a href="#post4622191">CAA-CZZ</a>, <a href="#post4622194">DAA-DZZ</a>, <a href="#post4622198">EAA-EZZ</a>, <a href="#post4622205">FAA-FZZ</a>, <a href="#post4622206">GAA-GZZ</a>, <a href="#post4622212">HAA-HZZ</a>, <a href="#post4622219">KAA-KZZ</a>, <a href="#post4622225">LAA-LZZ</a>, <a href="#post4622235">MAA-MZZ</a>, <a href="#post4626583">NAA-NZZ</a>, <a href="#post4636128">PAA-PZZ</a>, <a href="#post4651613">RAA-RZZ</a>.

You may notice that this thread has changed owners. I think we all owe Dandapani a "thank you" for keeping up with this information for the last couple of years. His old thead has been locked.

The purpose of this list is to be a resource for people who wonder what the “born-on” date of their Glock is, and to provide a historical record, which, if ever it is complete enough, can indicate some information about caliber trends, model popularity, production changes, etc.

To participate in this list, all you need to do is the following:

1. Peruse the list (REVIEW THIS PAGE ONLY) to determine if your serial number prefix (either two-letter for the older models or three-letter for the newer ones) is on the list. If its information is complete and correct, please don’t post.

2. Once you’ve determined you have useful information, please POST your information in the following order and format:

ABC - G-12 - January 2012 - 3rd Gen. - Other infor

For example: AA - G-17 - October 1986 - 1st Gen. - has Austrian markings

* Serial number Alpha-prefix (either two or three letters, depending on the age of your Glock). Please include ALL the letters at the beginning of the serial number.

* Glock model in this format: G-17, G-17L, G-19, G-20, etc. If it’s a “C” model, add the C.

* Born-on date, if known. If you’ve used Glock, Glockmeister, or another dating service, let us know its born-on date. If you have a newer Glock with the fired casings in an envelope, use the date on the envelope, as it’s always been accurate, compared to the dating services. If you live in a state where the dealer has to keep those/turn those i (MD, NY), ask him for the date, before he takes the envelope.

* Generation. This can be confusing. Please look at the picture below:
The SHOT ShowCase

- 1st Generation has the smooth, rounded “pebble-grip”.
- 2nd Generation has the “Grenade-style” checkering with NO fingergrooves (see picture).
- 3rd Generation has BOTH fingergrooves AND accessory rail on the front dustcover.
- If you have a subcompact (G-26, -27, -28, -29, -30, -33, -36) OR a “transition model” when Glock was putting fingergrooves but no accessory rail, then you have a 2.5 Generation. There is even a slight variation here, as some of the earliest G-26 & G-27s had smooth fingergrooves, without checkering in-between the grooves. Some people do not count the sub-compacts as 2.5 Gen since they came out after the 3rd Gen frames were already being made. Note: newer -29, -30 are now coming with rails.

The first Glocks with the finger groove frames were the G26 and G27.

The first Glocks that were originally made with generation three frames were the G34 and G35.
* Any special information you may know, such as if it is a commemorative, police-marked, has the new-style box, is affected by the frame recall, has Austrian proof marks, has the new loaded-chamber indicator extractor, has the 3rd frame pin (on newer G-17s), etc.

3. Please be brief and stick to that information which is needed.

Glock Pistol Upgrades

1990 Upgrade

Glock Model 19, 9mm Luger caliber, requires an upgrade for the following serial numbers:

AN, BP, BR, BV, BW, BX, DL, DM, DN, DP, DR, DS, DT, DV, DW, DX, DY, DZ
These pistols may have the potential of the action to malfunction as follows:
1. The slide locking back on a full magazine.
2. Failure to lock into battery because the barrel lug drags on the slide lock.
3. The magazine follower tips or sticks in the magazine tube.

1992, 6 part Upgrade

GLOCK, INC. Technical Bulletin #920403

April 1, 1992

Glock, Inc. announces a production change of the firing pin safety system. This new firing pin safety system has been installed in all production Glock pistols since November, 1991. A voluntary upgrade is being offered to maintain the Glock tradition of ensuring that all of our pistoils are up to the latest standards in 21st century Goock technology.

Most importantly, the components of the new firing pin safety system are not interchangable with the components of the old systam and Glock will always strive towards maintaining this feature of interchangability while working to ensure future interchangability.

The upgraded firing pin safety system consists of: the firing pin, firing pin safety, the extractor, the spring loaded bearing and the trigger bar. The upgraded system is applicable only to Glock pistols with the following serial number ranges :

Glock 17 - alpha prefixes AA - WF
Glock 19 - alpha prefixes through WJ
Glock 20 - alpha prefixes through WW
Glock 21 - alpha prefixes through XL
Glock 22 - alpha prefixes through YA
Glock 23 - alpha prefixes through SK

The upgraded firing pin safety has a new surface finish making it nearly 100% saltwater corrosion resistant. Also, after rigorous and extensive testing, the new system proves to be more durable and has a longer useful life. Here, as alwyas, Glock is working toward maintianing its standard of perfection.

1993, G19 Upgrade

Glock Model 19, 9mm Luger caliber, requires an upgrade for all pistols.

These pistols have the potential for an UNINTENTIONAL DISCHARGE of a cartridge with the action open.

The Glock model 19 pistol slide has a bottom protrusion, whose function is to push cartridges from the top of the magazine into the chamber. When the pistol is jammed in a double feed situation, the slide protrusion can come in contact with the primer of the jammed cartridge and cause UNINTENTIONAL DISCHARGE while the action is open.

2000, G26/27 Recoil spring upgrade

Glock Model 26, 9mm caliber, serial numbers DGU, DHR DKU.

Glock Model 27, .40S&W caliber, serial numbers DGD, DGV, DHS, DHT, DKV, DKW, DKX.

Mr. Don Bulver, warranty department of Glock, Inc., indicated the recoil springs produced before September 1999 may shear off on some of these pistols due to over hardness of the support tube.

Replacement springs will be distinguished by a vertical mark from the center on the front polymer portion of outer ring of the guide rod assembly, which will appear to be a mold line.

2002 Frame Upgrade – Rear slide rail

The GLOCK Corporation has identified a problem with a very small percentage of GLOCK pistols produced between September of 2001 and May of 2002. The specific problem that has been identified is the potential of breaking a rear frame rail in pistols manufactured during this time period. Within the specific range the breakage rate has been less than 0.0188%. So, while the actual percentage of rails reported broken is within any accepted manufacturing tolerance, it is not an acceptable situation to the GLOCK Corporation. It is also important to note that under most conditions GLOCK pistols will continue to function with three rails. A routine maintenance check after each time the pistol has been taken out and used would immediately indicate if there is a problem.

We are, therefore, concerned that a limited number of customers will not get the product we have promised them and what we have always delivered, the very best pistol on the market, in short, a GLOCK.

For these reasons, we have made the decision that in the interest of customer service, replacement frames will be offered to anyone who has a firearm in this range and decides to take advantage of this offer. The replacement frames will have identical serial numbers to our customer's original firearm except the numeral 1 will be added as a prefix. If you believe your firearm is within this range, please call 1-866-225-4098 to take advantage of the ultimate in customer service.

Nothing less than the best for our customers is acceptable to GLOCK and, as always, we will continue to work towards Perfection.

It appears that only serial numbers starting with "E", "GSSF", or "USA" (American Hero’s Commemoratives) are affected. In general, the chronological serial number set that has the prefix letters of "EKA" through "EVR" inclusive appear to be the affected Glocks, regardless of caliber. Three letters precede three numbers on a plate forward of the trigger guard on the underside of the polymer frame. However, some aberrations to this generalization have been reported by GTers. Reports are that the affected Glocks were manufactured from September 2001 to May 2002. So if you bought (or won a GSSF Glock) an "E" or "USA" series Glock in September of 2001 up until the present day, you might have an affected Glock. Unfortunately, Glock has not published a list. Hope this helps, but again, if you are responsible enough to own a gun and can read this, you are smart enough to check for yourself by calling Glock.
