Light Compatibility & Retention

This is a light-bearing Inside Waistband (IWB) holster designed for use with the following weapon lights:

• Streamlight TLR-7A
• Streamlight TLR-7X (requires #3 key)

Important: Retention is based on the weapon-mounted light. The holster will not retain the firearm without the light properly installed.

Fitment & Compatibility

• Retention requires the light: Locks directly onto the TLR-7A/TLR-7X with the #3 key. The pistol will not be retained without the light properly mounted.
• Not compatible with: P365 AXG & SXG grip modules, Icarus Air Polymer grip modules, or Norsso slides.
• Preferred light option: Streamlight TLR-7 X USB

Carry with confidence using our premium inside waistband (IWB) holster, precision-fit for the Sig Sauer P365-FUSE equipped 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.

This holster is designed to work with the factory slide. Any aftermarket slide design variations from the OEM slide dimensions will affect the holster fit and retention.
