Note: Icarus Precision supporting holsters are not returnable for anything other than quality or workmanship issues. They are specialty items for Icarus Precision Grip Modules used with factory slides, which impact fit and function of the holster. We do not guarantee fitment with aftermarket slides or other components.
This holster is specifically designed for use with the Icarus Precision A.C.E. 365 "XL" EVO Grip Module. Proper fit and retention depend on this exact configuration.
Icarus Precision A.C.E. 365 "XL" EVO Grip Module
This is a light-bearing Inside Waistband (IWB) holster designed for use with the following weapon lights:
Important: Retention is based on the weapon-mounted light. The holster will not retain the firearm without the light properly installed.
Important Fit Notes: This holster does not fit the P365 AXG & SXG grip modules. It is not compatible with Icarus Air Polymer grip modules and has not been tested with 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.
The compatible grip module can be found here: Icarus Precision A.C.E. 365 “XL” EVO Grip Module
The retention system secures on the light body, not the pistol—your firearm must have the TLR-7 X/A light mounted. Works with manual safety models. Designed for use with the #3 Key.
Our recommended light is the Streamlight TLR-7 X USB, available directly from us.
Engineered for performance under pressure, this Duty & Competition holster is built for the Sig Sauer P365XL with the Icarus Precision A.C.E. 365 "XL" EVO Grip Module and Streamlight TLR-7 X or TLR-7 A light. Designed for shooters who demand secure retention, fast access, and rock-solid stability for training, competition, or long shifts.
Every holster is trimmed, finished, and test-fitted in-house with real pistols and lights to ensure consistent performance. Built to deliver the dependable draw and retention serious shooters expect.
Maintenance Tip: Apply a removable thread locker to all hardware after setup to prevent screws from loosening during use.

This holster is awesome! Not many options for Icarus precision customizable side cars out there, had never heard of this company prior! Man am I impressed by the overall quality of this holster! Far more adjustable than anything else I’ve tried in this style(Tier1, Trex, LAS). I’m still adjusting to exactly how I like it about 2 weeks in. Only complaint I found is my optic (Swampfox Sentinel 2) did not fit and I did have to remove material around the optic to make it compatible. I know this isn’t a common optic so I wasn’t worried about it at all! Highly recommend you go buy this one
