Last, but not least, the “Glock 7,” which is a “porcelain gun that costs more than you make in a month!” jestera

Models by Caliber:
9mm:
17, 17L, 18, 19, 26, 34

.40 S&W
22, 23, 24, 27, 35

45 ACP
21, 30, 36

10mm
20, 29

357 Sig
31, 32, 33

45 GAP
37, 38, 39

380 ACP
25, 28

Model numbers by frame size:
Full-size
17, 17L, 18, 20, 21, 22, 24, 31, 34, 35, 37

Compact
19, 23, 25, 32, 38

Subcompact
26, 27, 28, 29, 30, 33, 39, 36 (-Slimline)

Extra Model Designations:
An “SF” after the model number indicates “Short-Frame” which is a reduction of the amount of material in the backstrap, for a better grip with smaller hands. (Currently, only G20, 21, 29 & 30 are available as “SF” models)
Note: the G21SF has been made in several variations, includng with or without an ambidextrous magazine release, and with either a standard "Glock" light rail OR a 1913 Picatinny Rail.

A “C” after the model number indicates that the gun is "Compensated" (ported) from the factory. Two small ports in the barrel with corresponding vents in the slide are present on either side of the front sight.

Generation Differences:
Gen 1: No finger grooves, no accessory rail, pebble-texture grip.
Gen 2: No finger grooves, no accessory rail, waffle-texure grip
Gen 2.5: Finger grooves, no accessory rail (only on some G29/G30’s)
Gen 3: Finger grooves & rail (no rail on 9mm/.40/357/.45GAP subcompacts, rail on .45ACP/10mm subcompacts)
RTF-2: Indicates a Gen 3 gun that has a very aggressive pyramid texture on the grip for use in weather/extreme situations.
Gen 4: Finger grooves & rail, interchangeable/mountable backstraps, has a less-aggressive “rough texture” pyramid-style texturing on grip (than the RTF-2 grips)

General Information:
Magazine interchangeability:High capacity magazines from larger Glock pistols will work in the smaller Glock pistols of the same caliber (they just hang out the bottom a bit). Example: A 17rd 9mm mag for a G17 will work in the subcompact G26. Exception: only G36 mags will work in the G36, as it is single stack, and will not accept hi-cap G21 or G30 mags.

Caliber interchangeability: A .40 caliber Glock can be converted to .357 Sig and vice-versa with a barrel swap to the other caliber. Example: To fire .40 S&W out of a G32, you would replace the G32 barrel with a G23 barrel. It is wise to use different magazines, marked with the correct caliber, as to prevent mixing ammo/bbls, but not absolutely necessary. Some aftermarket firms offer a 9mm conversion barrel for the .40/.357 Glocks, which require using the matching 9mm mags from the corresponding frame size. Example: G23 with a 40-to-9mm bbl would use G19 mags.

Default GLOCK model number descriptions

I look at it this way on top of all the models, Glock had donated money (now I may be wrong about the correct amount $124million) to the fight the small arms treaty that out president and hillary clinton are so proud of to take away our second amendment rights and have us be more like Europe.

If anyone knows of any gun or ammunition manufactures (in the USA)that have donated to the cause post it here I know of none

plus I have been a fan of glock when your life depends on the gun working flawlessly in the heat of life protection you can trust Glock ,(it's a work of art that works)

And just in case you didn't know.

The model numbers had nothing to do with the specific gun or caliber when named. They are the patent number.


Ie- the 17 is Glocks 17th patent.





And in addendum to the model identification-

Gen 1 guns have a black serial number plate, whereas all later models have the raw metal plates. Helps differentiate 1 and 2.

It has as much relevance as your post that deals with both models and generational difference.
