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. “X” MACRO, FUSE MACRO or FUSE EVO grip module. Proper fit and retention depend on this exact configuration.
You can view these grip modules directly through Icarus Precision:
Icarus Precision A.C.E. 365 “X” MACRO
Icarus Precision A.C.E. 365 "FUSE" EVO
Icarus Precision A.C.E. 365 "FUSE" MACRO
Not Compatible With:
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.
Built for shooters who demand speed, precision, and reliability, this light-duty & competition-style holster is custom-engineered for the Sig Sauer P365-FUSE Slide with the Icarus Precision A.C.E. “X” MACRO, FUSE MACRO or FUSE EVO grip module and Streamlight 1913 TLR-7 Sub light. Perfect for training days, competitive matches, and extended-duty carry, it delivers consistent retention, fast draws, and a rock-solid mount.
This holster is light-based retention only—the TLR-7 Sub (1913 version) or compatible models must be attached for proper function.
Firearm Models: Sig Sauer P365-FUSE Slide with Icarus Precision A.C.E. 365 MACRO Grip Module
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.
Light Models:
Use a removable thread locker on all hardware screws after setup to prevent loosening during carry.

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
