Cross-Compatibility with Glock 19 Slide and PSA Dagger

The Glock 43X slide does not fit Glock 19 or PSA Dagger frames.

The 43X uses a slimline frame and slide assembly, while the Glock 19 and Dagger use double-stack compact platforms. Frame dimensions and locking block designs are not compatible. Always verify compatibility before mixing parts between models.

What are Glock 43x OEM Slides Made of ?

FAQS

Q: Can I install a Glock 43X OEM slide on a Glock 43 frame?
No. The 43X slide won’t fit the Glock 43 frame due to differences in width and overall dimensions.

Q: Is the 43X slide compatible with the PSA Dagger?
No. The PSA Dagger is modeled after the Glock 19 and uses a wider double-stack frame. The 43X slide is built for Glock’s slimline platform.

Q: Does the Glock 43X OEM slide have an optic cut?
Only MOS models have a factory optic cut. Standard models do not.

Q: How often should I clean and lubricate my 43X slide?
Glock recommends cleaning and lubricating your slide after every use. If you don’t shoot regularly, clean it at least once a month to maintain performance.

Q: Will modifying my Glock 43X slide void the warranty?
Yes. Custom work like milling for optics or other alterations may void Glock’s warranty. Only unmodified, factory-original parts are covered.

Q: Can I legally convert my Glock 43X to full-auto?
No. Federal law prohibits converting any semi-automatic Glock, including the 43X, to full-auto. Doing so is a serious offense with legal consequences.
