This precision-built OWB duty and competition holster is engineered to fit the Sig Sauer P365, P365X, and P365XL equipped with the Streamlight TLR-8 Sub or TLR-8 G Sub (Sig version). Each holster provides a secure, repeatable fit and is fully compatible with manual safety models.
For correct lock-up and retention, this holster requires one of the following Streamlight TLR-8 Sub models made for Sig frames (not compatible with P365 X-Macro):
This holster utilizes light-based retention rather than firearm-based retention. It will not function unless the light is securely mounted.
For additional light specifications, see the Streamlight TLR-8 Sub Product Information.
Each holster is vacuum-formed around a precision CAD-derived mold of the exact firearm/light combination. After forming, every holster is trimmed, shaped, and hand-finished in-house. Final test-fit verification is done using the actual pistol and TLR-8 Sub to ensure correct retention and draw characteristics.
Retention can be easily adjusted to match your preferred draw feel. Red dot sights wider than the slide may experience clearance limitations.

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
