Ready to hit the range or carry with confidence? This outside waistband (OWB) holster is built for the Sig Sauer P365-FUSE with the Icarus Precision A.C.E. “X” MACRO, "FUSE" MACRO or "FUSE" EVO grip module. and a Streamlight TLR-7A or TLR-7X weapon-mounted light.

Fitment & Compatibility

  • Retention requires the light: The holster locks onto the Streamlight TLR-7A/TLR-7X with the #3 key and will not secure the pistol without it.
  • Not compatible with: P365 AXG & SXG grip modules, Icarus Air Polymer grip modules, or Norsso slides.
  • Preferred light option: Streamlight TLR-7 X USB

Key Features

  • Precision fit — CAD-modeled and vacuum-formed using actual P365-FUSE and TLR-7A/X components.
  • Light-based retention — Retains securely on the weapon light body, not the pistol itself.
  • Fully adjustable — Fine-tune ride height, cant, and retention to match your carry style.
  • Open muzzle — Accommodates threaded barrels and compensators.
  • Suppressor sight channel — Supports suppressor-height sights.
  • Red dot compatible — Clears most optics, including models that overhang the slide.
  • Comfort-forward design — Rounded edges reduce hot spots for daily carry and training comfort.
  • Made in the USA — Built in-house from durable .080" thermoplastic.

Build & Quality

Each holster is handcrafted, trimmed, and tested with actual firearms and lights to guarantee reliable retention and fit.
