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 β 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.
π§ 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.
π οΈ 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.
βοΈ Key Features:
-
Co-witness capable with RMR & Holosun red dots
-
Suppressor height design fits optic-ready pistol slides
-
Direct-mount compatible β 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 β even if your red dot fails.
