As a relative "newb" I found this to be quite helpful and refer to it daily.
I suppose everyone else has this memorized: I wish I was as smart as other people.
Just Saturday, I emailed someone with a Glock for sale for $400, and I thought I'd buy it to try it (small 9mm single-stack mag), but then I looked it up to be sure and I had gotten the Glock 42 (.380, which was the one for sale), mixed up with the Glock 43 (small 9mm that I was curious about and wanted to see if could replace my S/W M/P Bodyguard and/or Colt Mustang, which I don't like the Mustang).
I had to email back quickly to confess my stupidity.
I was on my phone instead of cmp where it is harder/slower to get connections and I was being lazy b/c I thought I was smart now (with the list).
Lesson learned.
It is very cool to see the 1/2" barrel difference in the 17 to the 19, warranting the 19 to be called, "compact."
Didn't know that.
I did see a 17L "long-slide" for sale weeks ago with its 6.2" barrel and said, "WOW! (at Marksman Shooting in Westfield).
I so wish people would put the caliber in instead of just the model of a gun for people like me who don't have it all memorized.
Everyday I have to look up calibers when looking at ads.
Actually, this must be an old list since anything 40 and up is not listed.

G17L/24 are "Longslide" models. They have the same frame as the G17/22, and have 6.2" bbls.
G34/35 are the "Practical/Tactical" models. They have the same frame as the G17/22, have 5.3" bbls, and are the same overall size as a 5" 1911.
Last, but not least, the “Glock 7,” which is a “porcelain gun that costs more than you make in a month!” jestera

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.
