I carry at 3 o'clock and it doesnt work well at that position. However, for appendix carry it does give better concealment.

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 "X" MACRO Grip Module. Proper fit and retention depend on this exact configuration.
Icarus Precision A.C.E. 365 "X" MACRO 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.
This Duty & Competition-style OWB holster is engineered for the Sig Sauer P365-XMACRO Slide paired with the Icarus Precision A.C.E. 365 "X" MACRO Grip Module and the Streamlight 1913 version of the TLR-7 Sub weapon-mounted light. Built for high-pressure performance, it delivers fast draws, consistent retention, and rock-solid stability whether you’re training, competing, or working a demanding shift.
Important Fit Notes:
Does NOT fit: P365 AXG & SXG grip modules, Icarus Air Polymer grip modules, manual safety models, or the SIG version of the TLR-7 Sub 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.
Not tested with Norsso slides.
The compatible grip module can be found here: Icarus Precision A.C.E. 365 “X” MACRO Grip Module
Light Required for Retention: Works only with the light mounted.

Its incredibly comfortable
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
