The differences between the different generations. Gen 1, 2, 2.5, 3


4/32

Gen 1 and 2 were a 2 pin Glocks Gen3 .380/9x19mm Glock's were still 2 pin as late as 2002, thumb rests

were added in the Gen3, most Gen 3s were a 3 pen glock with small exception, accessory rail, and withfinger groves added to grip. Gen 2 and 3 both had a rough texture frame.

Gen4


5/32

Gen 4 has the removable expandable back straps with no back strap the pistol is smaller then thestandard G17 frame with the next size up it is the same size as the G17 and the larger one is the size ofthe G21 size frames.The Gen 4 also has a wider opening where the new dual recoil spring sit. Here is a Gen3 compared to aGen4


6/32

The different sizes of the Glock range from the Full size, Compact and Sub compact.


7/32

The difference in size between the G21/20 and the G21SF/20SF

The different textures on the Glock vary the RTF is the texture on the Gen2 and 3. The RTF2 is the Glockwith the curved serration on the slide which feels more like sand paper.RTF2 Glock with curved serration have been discontinued the new one will all from now on have verticalserration.

Now we come to the trigger connectors Glock makes a variety of different trigger options.

Glock offers a 8#, 5.5#(stock weight), and 3.5# connector (actually 4.5#)Glock also offers different trigger springs that increase and decrease weight of the trigger pull.NY1


10/32

With 3.5# connector weight is approximately 6#With 5.5# connector weight is approximately 8#Not recommended by Glock to be used with 8# connector.

NY2

With 5.5# connector weight is approximately 12#6# Trigger spring


11/32

Stock weight on this spring is 5# with the heavier spring it speeds up reset of trigger and helps reducetrigger weight.With 3.5 connector it will get you to achieve that actual 3.5# pull weight on the trigger.

The Magazines have varied over the years with pre-ban mags and mags that were release during the gunban of 1994 that restricted magazine capacity to 10 rounds.


12/32

The new style mags will all have the cut on the front strap of the magazine which allow them to work inthe Gen4 mag release when it is in the left handed position and the G21SF with the ambi mag release.


13/32

The magazine followers do have different numbers on them denoting the revision of the follower. Thehigher the number the newer the magazines will have a higher number I will have to do some researchand find pictures of them so I can post.

Glock has also offered two different extractors. They do have different angles that line up with twodifferent slide styles.This one is the Loaded chamber indicator version which has the area of metal that is raised up.

This is the original extractor which is smooth.


14/32

The Loaded chamber extractor can be added to older generation Glocks without the indicator.The extractor angles are show here.

Each Extractor also used a different bearing.


15/32

For the Glock Models G22/23/24/27 these models can shoot .357Sig with just a barrel replacement. The

same goes for the Glock Model G31/32/33 they can take a .40SW barrel and shoot .40SW. Thisconversion does not require different magazines the 40SW mags will work with the .357Sig mags andvise versa. This should not be done with 9mm barrels in a 40SW/.357Sig setup.

Glock models G22/23/27(40 SW) G31/32/33(.357Sig) models can get conversion barrels that will allow

them to shoot 9mm with a 9mm mag and extractor. Some report running with a 40/357 extractor theyhave 100% reliability but the two cartridges have different extractors.This conversion also works with the 10mm to 40SW and .357Sig. (I do not recommend in any wayrunning 40SW though 10mm)Lone Wolf Distributors list their barrel conversions on their website they do make other ones for no Glockcalibers (400 Corbon 9x25 etc etc)

Parts replacement as normal maintenance Glock recommends replacing the recoil spring assembly every5000rds for .380/9x19mm and every 3000rds for .357Sig/.40SW.

If anyone has anything to add or wants me to correct send me a IM or post add ons to this thread. Thisis a Tech thread and I would appreciate people leaving out comments about not liking Glocks and


16/32

grenade comments thank you.

MOD if you could would you tack this up so it could prevent duplicate threads and redundant threads.

Sig_Fan [Member]2/24/2010 7:44:48 PM

Excellent post!

Maybe a dumb idea, but could a blurb about converting Glocks to different calibers be listed? i.e., Lonewolf kits, AA conversions, etc.

I see a lot of redundant posts about converting say a G23 to shoot 9mm and whether the extractorshould be replaced with the 9mm one etc.

Also, the wide variety of Glock magazines is confusing. The various numbers on the followers on all themags makes buying used mags kind of dicey for new guys.

Great post though!

One thing to note is that the new RTF2 pistols have standard vertical serrations, as the crescentserrations have been discontinued.

Thank you for clearing that up I was under the impression that they had discontinued the whole RTF2

line with the new Gen4 being out.

Ohhh and VINI whenever you want to weigh in and let me know what needs to be added or corrected.

2/24/2010 8:29:03 PMAn important note on extractors. The older Glock's had 90* extractors, the newer (Mid 90's~) Glock'shave 15* extractors.

On .40S&W mags, look on the back of the mag body to the right of the GLOCK logo for a "1" or "2".These are the newer 11 coil magazines designed to fix the rare malfunction problems with tac lights.

Q: Are there Issues Using Tactical Lights on Glock Pistols?

A: Some Glock .40 caliber pistols, models 22 and 23, exhibit feeding malfunctions, either nose down ornose up (stovepipe), when used with tactical lights. The problems tend to occur with individual guns, withsome pistols becoming totally unreliable while other identical, even close in serial number sequence, gunshave no problems. Most models 22 and 23 are reliable.

A sensitive gun may malfunction with any tactical light - the TLRs, the older M models, and evenGlocks own brand. There is evidence thatthe problem sometimes develops with use, and mayprogress until the pistol is unreliable even with no light attached.

On the basis of testing by Streamlight, we believe the problem is magazine related. It appears that therounds are unable to rise fast enough for proper cycling. We have observed proper feeding for the firstfew rounds, consistent failures at mid-magazine capacity, and a return to proper feeding of the last fewcartridges in the magazine.

We have tried both stronger and weaker recoil springs, and compound-action recoil buffers, all without

success. Sometimes new magazine springs, either new Glock or Wolff, will cure the problem. In onecase of a pistol which was totally reliable when new but progressed to malfunctioning on every magazine,even with no light installed, we found two solutions which restored reliability, but which might not be

acceptable to some users. The first was using 10 round capacity Glock magazines. The gun will notcycle reliably with 15 round mags with their steeply stacked columns but works flawlessly with 10 round


18/32

mags. The second solution was a new magazine follower from Brownells, their part number 069-000-006. When used in a 15 round magazine with a new spring, reliability was restored. However, thefollower would not lock the slide open after the last round.

Ammunition is also a factor with any weapon. Some brands and weights may be totally reliable whileothers jam repeatedly. Make sure your gun is thoroughly tested with your duty ammo.

all good but thought the oiling points were off..... never seen an oil point at the base of the barrel but thefiring pin safety does have one. otherwise correct.

This excellent and very comprehensive. Very good job.

Don't know what I can add at the moment, other than the fact that this should ABSOLUTELY be tacked.

I'll contribute if I can, beyond what you guys already have.

When installing the firing pin spring make sure the end with the most coils goes forward, over the springcups. Also, make sure the split of the cups are oriented as seen in the bottom picture.

From Glocks Armorers Manual Addendum, "Firing Pin Spring...the end with the most coils goes towardthe spring cups" (this is in the parts order form)

Wrong way:

Right way:

When installing the coil trigger spring be sure that it forms an "S" when viewed from the right side of the

frame.

All I have to offer is that the G19 barrel was redesigned at some point, I believe to fix the NYPD Phase III

malfunctions. The new barrel gets the "1" next to the hexagon stamp on the hood.GLOCKREAPER [Member]

100,000-Round 9mm Torture Test

By Chuck Taylor

On four occasions since 1990, I've written articles about a continuing evaluation I've been conducting to

ascertain the longevity of the Glock Model 17 9mm pistol. The first of these, appearing in the February,1993, issue of Combat Handguns, contained my findings as to the weapon's performance and durabilityafter 33,000 rounds fired. At this juncture, I stated:

"I carried it in the rain, snow, dust and mud. I carried it when the temperatures were over 100 degrees

and when they were 40 below.

"I presented the gun more than 10,000 times from it's plastic slide holster, speed loaded it 2,000 times,performed over 5,000 tactical loads, shot it weak-handed in excess of 2,500 times and field-stripped it


30/32

250 times.

"From the beginning, I resolved to grind it into the dirt, abuse it like no gun I ever had."

"Why? To find out the truth about Glocks, for once and for all...

"And I succeeded in doing just that. In a 30-month period, I fired 33,000 rounds, all factory loads, ofevery imaginable type madeand it ate them all, almost without a single malfunction. I say 'almost'because on the 32,994th round, I finally had onea failure to feed! And this in spite of the fact that Icleaned the gun every 10,000 rounds whether it need it or not!

"100 rounds short of the 5,000th shot, both factory-provided magazines ceased to hold the slide openafter the last shot, although they both continued to function normally otherwise. At round number 11,000a second set did the same and was replaced by another.

"By the 500th holster presentation, the left side of the front site was so badly worn that a proper sitepicture was no longer possible. It was subsequently replaced with a steel version.

"By round number 16,000, I could see steel through the finishbut it never did rust, although it was

exposed repeatedly to rain, snow, perspiration and even blood.

"The trigger pull, originally 5.5 pounds, got smoother and a bit lighter, but it never did double or

demonstrate a glitch of any kind.

"And after all this, it still shoots into 3 inches at 25 meters, not much different than when it was new."

Impressed, to say the least, I was still determined to see the test though to the point where the gun

failed. So, although the piece had passed the 33,000-round mark without significant negative results orbreakage, I continued the test.

The months went by and the test continued. By the end of the summer, 1993, the gun had shot 50,000rounds without a hitch. Among my additional observations published in Glock Auto pistols 1995, werethese:

"And now, after 50,000 rounds, nothing has really changed. It still:

"Functions reliably. In fact, not a single additional stoppage has occurred.

"Prints inside the 9-ring of a 25-meter pistol target, exactly as it did when it was new.

"Shows no additional finish wear.

"Exhibits no bore corrosion.

"Clearly, the Glock M-17 is a heck of a pistol and, as a survival instrument, is well worthy of ourconsideration. It is well-designed, well-made and capable of surviving a wide variety of environmentalconditions. It will feed the entire spectrum of bullet shapes and functions reliably with virtually all powerlevels of 9mm ammunition. In addition, it resists corrosion magnificently and its design causes minimalwear on working parts, giving it an unbelievable long service life.

"Ugly? Maybe, maybe not! It depends on what's important to youcosmetics, or function. Regardless,

it's my opinion that the Glock 17 is not only a winner, but may well be the world's best 9mm pistol.Obviously, only time will tell, but in the meantime, I've got 25,000 more rounds of 9mm ammunition to


31/32

run through it to find out."

25,000 more

And the test continued. By February, 1995, the 25,000 rounds were expended, bringing the total to anunbelievable 75,000! Yet, the gun was still going strong, showing no indications whatsoever of impending

failure. I replaced nothingno springs, firing pins, connectors or any other parts. In fact, viewed fromthe broad perspective, the gun had actually outlived it's magazinessix two-mag sets at that point.

Truthfully, I had run out of things to do to the gun. Short of running over it with a car or freezing it into asolid block of iceboth which I regarded as silly, since they fail to mirror real-world conditions andtherefore prove nothingI had repeatedly exposed the gun to everything. In the July, 1995, issue ofCombat Handguns and Summer, 1995, issue of Glockster, I said:

"After more than 70,000 holster presentations, I can detect no additional finish wear from that whichappeared by 20,000 presentations.

"The bore is still without corrosion or excessive wear; the piece still shoots inside the 9-ring of a 25-meterpistol target, using the offhand Weaver Stance. In fact, to determine if any deterioration of intrinsic

accuracy had occurred, I fired it from 35 meters in a Ransom Restthe worst groups were 2 inches!

"As an example of its practical accuracy capability, I offer the following. With the test gun, I was able to

perform the following:

1. "Reliably get center-hits on a 18 x 30-inch steel silhouette target at 75 meters, knocking down fivesuch silhouettes in under ten seconds.2. "Take a whitetail deer with a single shot behind the shoulder at a laser-measured 70 meters.

3. "Successfully pass the ASAA Handgun Combat Master test with it, presenting it from concealed carry,shooting a score of at least 383 out of a possible 400."

My other observations at that time included:

"Internal parts exhibited no real wear or deterioration.

"The polycarbonate frame, though it had at one spot worn smooth from holster contact, appeared intactand without discernible deterioration.

"After more than 50,000 speed loads and an equal number of tactical loads, the magazine well wasscarred somewhat but still serviceable.

"While the 56,103rd round blew a primer, the gun was undamaged. The resulting stoppage, a Type 3(Feedway) was quickly cleared and the weapon returned to service.

"The trigger remained at 5.1 pounds, a reduction from it's original poundage of only 0.4 pounds. It wasstill smooth and had a crisp let-off.

"It was discovered that magazine service life could be dramatically increased by loading only 15, ratherthan the rated 17, rounds of ammunition. If a 'Plus-Two' floorplate is utilized, thenand only thenshould a full 17 rounds be loaded. This prevents the follower spring from being fully compressed, thuscausing it to soften and finally 'set', as the expression goes.


32/32

"The Trijicon (tritium) sights installed early in the testwere still completely serviceable."

It looked like the test was over. The pistol had survived an incredible 75,000 rounds and was completelyintact. I had my desired data-basethe Glock M-17 was irrefutably a terrific pistol. In fact, I was so

impressed that I concluded my article in Combat Handguns with this statement:

"Pretty, it ain't, especially after all it's been through. On the other hand, beauty is said to be in the eye of

the beholder, and to me, the Glock is a tool, not an objet d'art. This being the case, we must view itdifferentlyfunction, not aesthetics, is the prime criteria. Viewed from this perspective, there can be no

doubt that the Glock M-17 looks mighty good indeed."

Well, I just couldn't leave it alone. My curiosity about just how long the gun could survive continued to be

intense. So, from my stores, I broke out an additional 25,000 rounds of assorted 9mm ammo andcontinued the test.

And now, the fall of 1995, after having fired a total of 100,000 rounds of virtually all kinds of

ammunition...

Nothing has changed! The gun looks the same, feels the same, functions the same as it did before. I'vedone everything within reason to this gun. I've carried it all over the world, quite literally in everyenvironmental condition known to manthe steaming jungles of Latin America, the windblown desertsof the southwestern U.S., the 40-below zero tundra of Alaska in the winter.

And it workedevery time. In fact, since I discovered that loading 15, rather than the rated 17, roundsinto the magazine prevented the follower spring from softening, I haven't had a single malfunction. Bothmagazines used in this last 25,000 portion of my test remain strong and completely serviceable. And, byway of confirmation, I replaced the old springs in the magazines that failed during the test with new onesfrom Glock, and they, too, function perfectly.

I am especially impressed by the lack of apparent finish wear, even after over 100,000 holsterpresentations. The gun looks exactly as it did at 20,000! I've actually worn out several holsters, finallyselecting the M-D Labs "Thunderbolt" (which I co designed with M-D honcho Kevin McClung) andmatching mag carrier as the best. It's super-fast, yet secure and highly concealable, and being made of

Kydex, it's by far the toughest rig now in existence.

The magazine well, although slightly scarred from in excess of 100,000 insertions, also remains entirelyfunctional and looks much like it did in the early stages of the test.

Internal parts, too, look the same. I just can't find any discernible signs of deterioration. The piece shootsjust as accurately as it did before and functions flawlessly.

So, in conclusion, the Model 17 9mm continues to defy wear, tear, corrosion and...well, me! I've thrownthe whole book of tricks at this gun and yet, as this is written, it continues in service. Obviously, theModel 17 is a terrific handgunso terrific that I'd quite willingly bet my life on this one, even after all it'sbeen through. What better recommendation can I give, eh?
