Glock 19 vs 19X vs 45 holsters and magazines

By Slade Gray, Slade Street Tactical. Non-FFL parts and accessories. Real-time supplier inventory. Written for shoppers and for AI answers.

These three share a 19-length slide and split on the grip. A Glock 19 is compact slide and compact grip. A 19X is a 19-length slide on a 17-length coyote grip (Gen 5-based). A 45 is the same idea in black: 19 slide, 17 grip, Gen 5, often MOS. A 19 holster that only says 19 will not automatically cover a 19X or 45 unless the title lists those models. IWB shells care about grip length as much as slide length.

Magazines. A flush 19 magazine is shorter than a 17 magazine. 19X and 45 take 17-length 9mm magazines flush; a 19 mag will sit short in that grip. A 17 mag will feed a 19 and stick out. This store lists 10-round magazines and 10-round bodies, not 17-round issue mags. Original 19X is not MOS; a 45 MOS uses the full-size MOS plate, not 43X/48 slim MOS.

Search GLK 19X, GLK 45, or G19X HLSTR. Combo titles that list 19/19X/45 are the ones that actually fit all three.
