Precision Build & Fitment

Each holster is vacuum-formed on precision-machined molds developed from CAD models of the actual firearm. After forming, every unit is trimmed, folded, and finished in-house to ensure consistency and smooth edges.

Final fit and retention testing is performed using the real firearm to confirm proper lockup and reliable draw. Retention can be easily tuned to your personal preference.

This inside waistband holster is engineered for the Sig Sauer P365-FUSE slide when paired with the Icarus Precision A.C.E. 365 “X” MACRO, A.C.E. 365 "FUSE" MACRO, and A.C.E. "FUSE" EVO Grip Modules. It provides a secure, comfortable concealed carry solution tailored to these upgraded grip systems.

Not compatible with P365 AXG or SXG grip modules, Norsso slides, or any Icarus Air Polymer grip modules. This holster does support manual safety models.

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.
