How are Glocks Numbered? By Patent of Course

Have you wondered how Glocks are Numbered?  I have.  However, I constantly get asked what I think about the Glock 324B* or some other obscure number

I never bothered to memorize the Glock numbering scheme. I just ask for a specific size and caliber.  Since, I prefer a compact 9mm.  Therefore, I typically buy a Glock 19.

The reason I don’t keep up with the numbering system is that it does not make sense for the user.  They are not numbered in order of caliber or size. 

Glocks are numbered by the order Gaston Glock gets patent number.  I would prefer them listed by caliber and size.

Why not put all the 9mm guns in a row, then number by size.  Glock 1, 2, and 3 could be the standard, compact, subcompact.   Then the 4,5, and 6 could be the .40 S&W guns.  Next could come the .45 ACP in the 7, 8, and 9 models.

That would be much easier for me to remember.  In contrast, the reason Glock pistols start at 17 is that Gaston Glock had 16 patents before guns.  He originally made polymer kitchen utensils before he decided to go after an Austrian military contract for a new pistol.

(* I made that number up.  There is not a Glock 324 but I expect some day Glock may make one)

Here is a Basic Breakdown

  • Glock 17 is a 9mm full size
  • The 18 is the select fire version
  • Nest, the Glock 19 is the 9mm compact
  • 20, 21, 22 are all full size, with the 20 chambered in 10mm, the 21 in .45 acp, and the 22 in .40 S&W
  • 22, 23, and 24 are all .40 with the difference being size.  The 23 is compact, the 24 is sized for competition.
  • Glock 25 is a compact .380
  • 26-30 are all sub compacts.  In order of caliber, they are: 9mm, .40, .380, 10mm.  Lastly the 30 is a .45acp
  • 31, 32, and 33 are all chambered in .357 sig.  the 31 is fill sized, the 32 compact, and the 33 is subcompact.  This is the series the TN Highway patrol carries.
  • 34 and 35 are competition guns.  the 34 is 9mm.  the 35 is .40 S&W
  • The Glock 36 is a slimline .45 acp
  • Lastly, the 37, 38, and 39 are chambered in .45GAP.  the 37 is the standard full size, the 38 compact, and the 39 the sub compact.


How to Replace A Glock Trigger to Make it Smooth

I do not believe in modifying carry guns outside of factory specifications. A small part of this is because of liability, but mostly it is because of the unknown consequences to reliability.

A firearm is a machine, and the weight of the parts of the gun are factored in with drag, inertia, spring weight, type of ammunition, and hundreds of other factors to create a gun that functions with the desired ratio or accuracy and reliability.

Every part has to work together and when you replace a part you are piddling with the whole. Tiny tolerances add up – and when you replace many parts you may end up with an unreliable gun. Since the most important factor in choosing a defensive handgun is reliability I don’t risk compounding tolerances.

The Smooth Trigger Was What Glock Designed

However, the modification in todays post is actually bringing the gun back to manufacturer’s specifications. When Gaston Glock created his pistol he built it with a smooth faced trigger, but due to some unfathomable reason the ATF has import points and for a gun to able to be imported it has to have enough points. The ATF considers a smooth trigger to be a combat trigger, and a ridged trigger to be a target trigger.

A full sized Glock has enough points to be imported with the original trigger, but the compact and sub-compact guns were one point short. Therefore Glock has to make a target trigger to meet the red tape.

Luckily, many (if not most) of Glock parts are interchangeable, and if you want a smooth trigger for your compact or sub compact all you need to do (in most cases) is to order the trigger from the full size gun in your caliber.

I have a Glock 19, so to get a smooth trigger I just ordered the Glock 17 trigger and swapped them.  It only cost me a few dollars and a couple minutes to change the feel of my trigger pull.

Now this does nothing to change the weight, take up, or break of the action.

If only changes the feel of the trigger on your finger. However if you are going to a high round count school where you will spend 8 hours a day on the range shooting hundreds or thousands of rounds you will feel a difference, and you will be thankful you made the switch. Other than that it is really a personal preference thing and just something nice to know.

How to Use the Glock Trigger Reset to Shoot Better

Many striker fired guns (such as Glock) have an interesting feature to them.

When the striker is in its operating position, and the trigger is fully forward you have quite a bit of travel until the trigger actually engages and fires the handgun.

However, after you fire the gun, if you do not let the trigger out fully and simply let it move forward enough to reset, the next shot is much faster as the trigger has very little distance to move.

This is called trigger reset.  It is one thing I really like about Glocks.  When you master the process, you can shoot much faster with more accuracy.

How to Use the Glock Trigger Reset to Shoot Better

  • Clear your handgun
  • Remove all ammunition from the room you are dry firing the firearm
  • Visually and physically inspect the chamber to ensure the firearm is clear
  • While pointing the handgun in a safe direction, pull the trigger and keep it pressed all the way to the rear.
  • While holding the trigger, rack the slide
  • Slowly, and with your finger on the trigger, release the pressure until you hear (and feel) a click. This is the trigger reset. Once this click is heard the trigger is reset and the handgun can be fired again.
  • Dry fire the handgun while pointing it in a safe direction. Did you notice the difference in trigger feel and amount of trigger pull needed?

The Glock cycles at approximately 1200 rounds per minute.  Even the fastest shooter cannot manipulate the trigger anywhere close to that. The firearm will cycle before you have a chance to release the trigger, period. All you need to do to take advantage of this is to train yourself not to fully disengage the trigger and only release enough pressure to reset it.

If you do this you will be able to fire faster and with more control.

I have taught this for years, but the more I learn the more tools I have. I recently learned that Glock designed his pistol to function with this trigger reset even if the firearm had damage. If the “S” shaped trigger return spring breaks, or falls off due to improper install the firearm will fire using the trigger reset technique. As long as the slide cycles with the trigger held to the rear, the firearm will function. However, if the trigger is not held back, the trigger will not reset, and the gun will not fire.

No worries though, Gaston Glock thought of that too. If you do not use trigger reset and the trigger return spring is broken, to get the gun to work simply press the trigger rearward and cycle the slide.

Not everybody likes Glock firearms, just like some people don’t like computers. But anyone that has an open mind has to realize that a Glock pistol is very well designed – you might not like the reasons for some parts of the design, but the gun works exactly as it was created to.
