FAQs

Q: Is the Glock 45 slide compatible with Gen 3 or Gen 4 frames?

No. Gen 5 slides like the G45 feature unique internals that don’t match Gen 3 or Gen 4 frames.

Q: Can I mount a red dot on the Glock 45 OEM slide?

No. The standard G45 slide does not include an MOS cut. For optics, choose the Glock 45 MOS model.

Q: Does this slide fit the PSA Dagger frame?

Not directly. While some users report limited compatibility, the G45 slide may require fitting or result in cycling issues on the Dagger frame.

Q: Will this slide work on a Glock 19 Gen 5 frame?

Yes. The G45 slide and the Glock 19 Gen 5 share compatible dimensions and internals.

Q: How often should I clean and lubricate the slide?

Glock recommends cleaning and lubricating your slide after every range session, or monthly if unused.
