On the left is a gen 2 glock bbl bought about 1999. In the middle is a gen 3 glock bbl bought this year and on the right is an aftermarket bbl.  I measured the chambers, The after market bbl chamber measured average .428. Both glock chambers measured average .432 so it appears the chamber was left unchanged other than the modifications to the chamber mouth and significant changes to the depth and width of the feed ramp. The changes give better support to the case head as you can see. Ricky |

Copy/Paste from the Glock Recall Thread http://glocktalk.com/forums/showthread.php?t=412093 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. |

In addition to the large article of 100,000 round test, there is a great Youtube video of a glock 10,000 round test. Just search Glock 10,000 1000 tourter test.
The instructer and a second shooter fire 10,000 1000 rounds out of his service pistol. I can't post the link right now because of work, I'll update it when I get a chance at home. It's worth a watch for anyone who has doubts about these weapons. I owned a Glock 19 in 1991, and just bought a Gen 4 G22. Loved the old one and love the new one even better, just need some night sites on it. Also in reference to the RTF if you have not really felt it, the Gen 4 is not nearly as aggressive as the RTF 3 is really really aggresive and had the opertunity before I bought my new one to feel all styles and liked the Gen 4 better. One last thing I'll add to update is a set of pictures showing the different mag releases. I know it's larger on the Gen 4. You have great shots of all the other changes but missed that one. It's something to look at when buying a new Glock. http://www.youtube.com/watch?v=0_JuF23qazI Edited cause I got 0 happy and added the link. Two segments, enjoy. |

I have a Wolf and a Zevtech that are both even on coils...what to do????????????????

Prices went up a little bit a few months ago. I want to say from 398.20 to 425.00 for the standard fixed sight models. |

I think that the greatest lesson learned from this trip is that most interwebz-commandoz would be far better served calling Glock Customer Service for answers to questions than they are arguing with each other in the ARFCOM Glock Forum, or on Glock Talk. Further, the interwebz has not, in any way/shape/form, promoted patience in the market. I truly feel a bit more sympathy for Glock, Magpul, BCM, Spike's Tactical, Bushmaster, and other firms who have taken the immature wrath of the interwebz-commandoz. That said, here are some of my notes, which will hopefully address the most urgent concerns of the more serious-minded Glock fans. –––––––––––––––––––––––––––––––––––––––––––––– Generation 3 vs Generation 4

What is the BATF points system and how does it affect Glocks? Many of the Glock's parts and sometimes the whole gun are dictated or limited by the BATF's system of "import points". To qualify for import a pistol must score 75 points based on the following system:
Changes and features made to Glocks to comply with the BATF rules: - all models are imported with a cheap click-adjustable rear sight that is replaced at the factory with the stock sight - target (grooved) trigger added to compacts & subcompacts - target grips added to all models (required for the subcompacts) - due to their caliber, .380 autos (G25 & G28) do not score enough points to be imported Courtesy of Glockfaq.com |
Once we were a Nation of Riflemen
I just got a Gen3 G19 as a gift today that was manufactured in 1998. It came with three "ban" mags (still have the LEO/MIL only stamp on them). Two have "9mm1" on the follower, and one has "9mm3," denoting the changes made as mentioned in the OP. I will try to get some photos up to show the difference in the followers soon and you can add them to the OP as well.

As a new Glock owner this was Very Informational. Don't really plan to change/upgrade anything, except maybe adding NS. |

Rather than add another response to thread, I will just state here that I was able to dig out my old receipt and I did in fact purchase it 7/13/98 for $405.00.

The early "wasps tail" slide lock spring (left) is know to occasionally break, causing the slide assembly to slide off when the trigger is pulled. In the late '90's, Glock modified it by making it full thickness and breakage with the new slide lock spring (right) is no longer a problem.  |

I know this isn't vital info but you CANNOT convert a glock 17-19-26 into a 22-23-27 the larger barrel will not fit into the slide
I took a buddy shooting and he shot my 23 converted in both 9 and 40 and decided thats what he wanted so when he went to buy one the store clerk told him the only difference in the 23 and 19 is one came with a 9barrel te other with a 40 so he bought the 19 and cannot convert it |

Although Glock only recommends it for the Gen 4 it is being installed in the older pistols and IMO gives the best trigger I have tried so far. |

I found a website that has pretty up-to-date serial number prefixes unlike the dead GlockTalk serial number thread:
http://www.stakhaus.com/ |
| A magazine comment/question: I have a G17 magazine that is similar to your second of 8 magazines shown on page one. It has a floorplate with no Glock logo. The floorplate does not accept an insert. Any idea when the floorplates started getting the logo on them? |
