A Glock 26 barrel requires a Glock 26 slide,. If you want to convert a Glock 27 to 9 mm without changing the slide, you'll need a 9 mm, "conversion" barrel for a Glock 27. A conversion barrel for a Glock 23 will work but will be a half inch longer. A Glock 22 conversion barrel will not work in a Glock 27 though.
Despite some media reports, there were no AK-47s involved in the incident
