    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.
