🔍 What Is a Glock 19 Red Dot Slide?

A Glock 19 red dot slide is an upgraded slide that has been CNC machined with an optic cut, allowing for direct mounting of reflex sights like:

• ✅ Trijicon RMR Type 2

• ✅ Holosun 507C / 407C

• ✅ Swampfox Liberty / Justice

• ✅ Leupold DeltaPoint Pro (on select models)

These slides eliminate the need for adapter plates or slide milling, saving you time and giving you a low-profile, rugged, and repeatable zero.
