Sig Sauer P365-FUSE & Icarus Precision A.C.E. Module & TLR-7 X/A Duty & Competition Holster

Engineered for performance under pressure, this light-duty & Competition-style holster is built for the Sig Sauer P365-FUSE paired with the Icarus Precision A.C.E. 365 “X” MACRO or FUSE EVO grip module and the Streamlight TLR-7A or TLR-7X weapon-mounted light.

Whether you’re training, competing, or working a long shift, this holster delivers dependable retention, fast access, and rock-solid stability—built to meet the demands of duty use and the rigors of competition.

The light is required for retention. This holster secures to the TLR-7A / TLR-7X (mounted with the #3 key). It will not retain the pistol without the light properly attached.

Our preferred light option for this holster is the Streamlight TLR-7 X USB, which can be purchased from us HERE

Note: This holster is not compatible with Icarus Air Polymer grip modules and has not been tested with Norsso Slides.

Key Features

• Precision fit – CAD-modeled and vacuum-formed using actual P365-FUSE and TLR-7A/X components for unmatched accuracy.
• Light-based retention – Secures onto the light body, not the pistol itself.
• Fully adjustable – Fine-tune ride height, cant, and retention to suit your carry style.
• Open muzzle – Allows for threaded barrels and compensators.
• Suppressor sight channel – Supports taller sights with ease.
• Red dot compatible – Clears most optics, including those that overhang the slide.
• Comfort-forward design – Rounded edges and smoothed surfaces minimize hot spots and improve daily comfort.
• Made in the USA – Built in-house using durable .080” thermoplastic.

Additional Details

Every holster is handcrafted, trimmed, and tested in-house with actual pistols and lights to ensure a perfect fit and consistent retention.

We strongly recommend applying a removable thread locker to each screw after setup to prevent hardware loosening during carry.
