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 & Requirements

• Light required for retention: Secures to the TLR-7A / TLR-7X body and will not retain the pistol without the light properly mounted.
• Key used for testing: Mounted with the 1913-3 key during in-house validation.
• Grip compatibility: Designed for Icarus A.C.E. 365 “X” MACRO, FUSE MACRO and FUSE EVO modules; compatible with manual safety models.
• Not compatible with: P365 AXG & SXG grip modules, Icarus Air Polymer grip modules, or (not tested) Norsso slides.
• 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.

Preferred Lights & Documentation

• Purchase the recommended Streamlight TLR-7 X USB
• Streamlight documentation: TLR-7X Data Sheet

Engineered for performance under pressure, this light-duty & competition-style holster is built around the Sig Sauer P365-FUSE paired 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.
