Back Up Iron Sights for RMR / Holosun on Glock & Walther PDP Slides

If you're running a red dot like the Trijicon RMR or Holosun 507C on your Glock or Walther PDP, don’t skip your backup iron sights. These low-profile sights are designed to provide a clean co-witness with your optic — no clutter, no compromise, and no need for extra milling.

Perfectly suited for optics-ready and direct milled slides, these backup sights give you a fast, reliable aiming solution when it matters most.

🔧 Designed for RMR & Holosun Optic Cuts

These back up sights are specifically engineered to work behind red dots mounted on:

• Glock MOS slides

• Walther PDP optics-ready slides

• Custom direct-milled slides cut for RMR footprint optics

Whether you're mounting a Trijicon RMR, Holosun 407C, 507C, or 508T, this sight system ensures compatibility and clarity in your sight picture.

🛠️ Why These Back Up Sights Are Different

Most “universal” iron sights either sit too low to co-witness or too high and block your red dot window. These are purpose-built to offer the ideal co-witness height with minimal visual obstruction.

✔️ Key Features:

• Co-witness capable with RMR & Holosun red dots

• Suppressor height design fits optic-ready pistol slides

• Direct-mount compatible — no extra plates needed

• Fast target acquisition even in low light or optic failure

• Steel construction for durability under recoil and stress

These backup sights give you the confidence to stay on target — even if your red dot fails.
