Home / Guides / Glock 19X and 45 Holster Fit: The Full-Grip, Compact-Slide Glocks
The 19X and the 45 are the mashup Glocks: a 17-length grip on a 19-length slide. That combination is excellent to shoot and awkward to holster, because it breaks the assumption that Glock holsters are interchangeable.
| Model | Slide | Grip | Frame |
|---|---|---|---|
| Glock 19 | 4.02" | Compact | Compact |
| Glock 45 | 4.02" | Full (17-length) | Compact dust cover |
| Glock 19X | 4.02" | Full (17-length) | Compact dust cover, lanyard loop |
The slide is identical to a 19. The grip is identical to a 17. In a holster, that means the body should be sized like a 19 but the retention and belt clearance must accommodate a taller grip.
The grip is your print. Everything else is management.
Many 45 and 19X pistols are MOS. If you run a dot, the holster needs an optic cut. MOS plates vary in height, so verify the cut clears the plate and optic combination you actually use — not just the slide.
Try your 19 holster first if you have one, and check the three things above. If it holds firmly with the pistol upside down and you have no interference with the lanyard loop or beavertail, use it. If the grip makes the whole rig unstable, buy a body designed for the full-grip frame.
Often the slide fits, but the full-length grip changes concealment and sometimes causes interference at the beavertail and lanyard loop. Test retention and comfort before relying on it.
Both are a 19 slide on a full-length grip. The 19X has a coyote finish, night sights, and a lanyard loop; the 45 is closer to standard Glock finishes and sights.
Yes. Same slide, taller grip. The grip is the part that prints, so a 19X or 45 hides less easily than a 19 in the same clothing.
Verify the holster clears it. A tightly molded holster or tall sweat guard can interfere with the loop and cause inconsistent seating.
Yes. MOS models are optic-ready. The holster needs an optic cut that clears both the MOS plate and the optic.
