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.
http://www.glockfaq.com/gunsmithing.htm#slideframe The 23 receiver is not compatible with the 38 slide.
IIRC it is the Glock Model 23.
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.
Different calibers. The Model 19 is in caliber 9x19mm, the Model 23 is a .40 caliber. The 19 holds more ammo in the standard magazine. External dimensions and weight are the same.
It depends on the model. According the Glock website, the 27 holds 9, the Glock 23 holds 13, the Glock 22 holds 15, and the Glock 35 holds 15.
A new one retails for about 500 dollars.
