Question: are glock 22 and 23 magazines interchangeable?
Answer: The Glock 22 and the Glock 23 are both semi-automatic handguns chambered for . 40 S&W. ... The extra size allows for 15 rounds in the standard magazine while the Glock 23 allows for 13 rounds. The magazine for the 22 can be used in the 23 but the smaller magazine cannot be used in the 22.
