Will a Glock 43X fit a Glock 26 holster?
Usually not. The Glock 43X is a slimline single stack frame and a Glock 26 holster is molded around a double stack frame, so the fit and retention will be wrong. Holster makers mold for exact models, so check the maker's fit list before you buy.

Glock puts the Glock 43X in its subcompact slimline class and the Glock 26 in its subcompact class. Here is every current Glock at the same scale.
