FAQs
Q: Can I use a Gen 4 Glock 19 slide on a Gen 3 frame?
No, not without modification. Gen 4 slides and Gen 3 frames have different internals and may not align correctly.
Q: Will this slide fit the PSA Dagger frame?
No. The PSA Dagger is based on the Gen 3 design and does not support Gen 4 slides without adjustment.
Q: Does the slide come optic-ready?
Only the MOS version comes with a factory optic cut. The standard version does not.
Q: How often should I clean and lubricate my slide?
Glock recommends cleaning and lubricating the slide after every use. If unused, perform maintenance at least once a month.
Q: Will custom modifications void Glock’s warranty?
Yes. Permanent alterations such as milling or refinishing may void the factory warranty. Always check with Glock before making changes.
