Yes, a Glock 19 9mm magazine can be used on a Glock 23 since both firearms are chambered in 9mm.
No. Some .40/.357 Sig pistols can be converted to fire 9mm simply by dropping in a 9mm barrel and using the 9mm magazines, though. Not sure about the Glock.
No. The 9mm is not compatible with the .40 caliber frame/slide. On the other hand, you can put a .357 SIG barrel into a Glock 22 and use your .40 magazines.
The Glock 17 (full-size 9mm) holds 17 rounds in a factory magazine. The Glock 19 (compact 9mm) holds 15 rounds in a factory magazine. The Glock 26 (teeny-tiny 9mm) holds 10 rounds in a factory magazine. The Glock 17L/34 (competition) also holds 17 rounds.
No, the Glock 22 barrel has an outside diameter that is larger than the hole in the front of the Glock 17 slide. your safest option is to buy a Glock 22 and a 9mm conversion barrel for the 22 slide. Then with the correct magazines you could use either 9mm or .40 S&W in a single frame and slide.
The Glock 17 (full-size 9mm) holds 17 rounds in a factory magazine. The Glock 19 (compact 9mm) holds 15 rounds in a factory magazine. The Glock 26 (teeny-tiny 9mm) holds 10 rounds in a factory magazine. The Glock 17L/34 (competition) also holds 17 rounds.
No, they are different calibers. A Glock 17 is 9mm and a Glock 23 is .40 S&W. A Glock 22 magazine would fit in a Glock 23.
If you change out the barrel. Yes, it is compatible. It's a drop in barrel. There are no mods needed and it uses the same magazine and firing pin.
No. Because a Glock 26 is chambered in 9mm, as a Glock 23 is chambered in .40 s&w. For example you can use a Glock 22 (full size) in Glock 23 (compact) and in Glock 27 (sub-compact) But you cannot use Glock 27 mags in Glock 23 or Glock 22.
There's no Glock with the model number "9", so I assume you mean a 9mm glock. The Glock 17 (full-size 9mm) holds 17 rounds in a factory magazine. The Glock 19 (compact 9mm) holds 15 rounds in a factory magazine. The Glock 26 (teeny-tiny 9mm) holds 10 rounds in a factory magazine. The Glock 17L/34 (competition) also holds 17 rounds. The Glock 18 (Select fire, full size 9mm) holds 33 rounds in a factory magazine. Higher capacity magazines fit and function in lower capacity firearms, for instance the model 26 can use model 17, 19, and 33 magazines.
The Glock 34 is a 9mm pistol. It has a 5.32" barrel (which is 0.82" longer than the Glock 17) and a longer slide, extended magazine and slide releases with a reduced trigger pull. The longer slide gives quicker recovery between each shot.
This seems to be a persistent myth. The .40 S&W/.357 Sig magazines are not compatible with 9mm Glocks.
