The quick answer, yes.
Thesub and compactmodels will fit holsters designed for the full-sized.
The "Slide" version allows you to use one holster for similar guns of different lengths (such as Glock 26, 19 and .17).
The Slide is typically slightly longer than the shortest gun of the series, and left open so the excess barrel length on longer guns can "slide" through the end of the holster.
A "Full-Coverage" version can be ordered by selecting your specific gun model.
This Comp-Tac holster will accommodate all the Glocks except the 20/21/29/30/36
