I would guess restricted states or countries, & people like having the slimmer profile & longer slide maybe. I have the 43X, but carry a Glock subcompact over it. Who knows, lol!Maybe it's just me but,
since the 43, 43x, 48 and whatever else has been made by Glock lately, why has the G26 became an item of the past?
It is a solid shooter IMHO.
