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.
Fits Sig Sauer P365, P365X, and P365XL with Icarus Precision XL EVO Grip & Streamlight TLR-7 Sub 1913
The holster does not fit the P365 AXG & SXG grip modules.

For secure fit and reliable retention, the correct 1913 version of the TLR-7 Sub must be mounted to the firearm.

Will this holster fit the P365 without a light?
No. This holster requires the Streamlight TLR-7 Sub 1913, TLR-7 X Sub, or TLR-7 HL-X Sub to be installed. The holster retention is based entirely on the light, not the gun frame.
How do I know if I have the 1913 version of the TLR-7 Sub?
Check your light’s part number. It must be #69402, #69407, or #69505. These versions include the #1 1913 key, which is essential for proper fit and retention.
Is this holster compatible with the Icarus AIR grip module?
No. It is only compatible with the Icarus A.C.E. 365 XL EVO aluminum grip module, not the AIR Polymer series.
Does it work with the Phlster Enigma?
Yes, this holster is fully compatible with the Phlster OS Enigma system.
Can I use this holster with a compensator or threaded barrel?
Yes. The open-muzzle design accommodates extended barrels and comps without issue.
Is this holster red dot compatible?
Yes. The sweat guard is cut to clear optics like the RomeoZero, Holosun EPS, and others, even those that overhang the slide.
What ride height and cant adjustments are available?
The holster supports adjustable ride height and cant through both Monoblock and Ultituck belt clip options.

Gets the job done, nothing special about it had to add a wedge after market, they shoukd offer them
Very nice holster. The retention is a little tight especially with the modwing screws tightened up. But its comfortable and the adjustability of the belt clip is fantastic.
This is my 2nd Four Bros holster. The holster shipped and arrived much quicker than expected. The fit/finish, aestetics, and retention are all top notch and the fact that they manufacture an Icarus precision model really makes me a happy customer. I have purchased several quality kydex holsters from well known companies in the past, but Four Bros has won me over. Thank you for making a quality holster that is affordable. I will be a customer for life.
Perfect fit, comfortable, conceals well, minimal footprint.
My gun fits perfect in the holster. It works great for appendix carry.
The belt loop attachment is painful, it digs into me. I would not recommend this attachment.
Solid fit. Good, and adjustable, retention.
It got here quickly and was a perfect fit!
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
