Glock 19 Gen 5 MOS Slide FAQs

About the MOS System on Compact Slide

Q: What optics mount directly without plates?

A: Yes, complete slides include Glock’s full MOS plate set for RMR, Holosun C, Leupold, and other popular optics.

Compatibility Questions

Q: Will this work on my Gen 4 Glock 19 frame?

Technical Details
