Sig Sauer P365-FUSE & Icarus Precision A.C.E. Module & TLR-7 Sub OWB Holster

Sig Sauer P365-FUSE Icarus Precision A.C.E. “X” MACRO / FUSE EVO OWB Holster – TLR-7 Sub Series Compatible

Overview

Designed for competitive shooting, range use, and everyday carry, this Outside Waistband (OWB) holster is custom-built for the Sig Sauer P365-FUSE with the Icarus Precision A.C.E. “X” MACRO or FUSE EVO grip module. Engineered for use with the Streamlight TLR-7 Sub, TLR-7 X Sub, or TLR-7 HL-X Sub weapon-mounted lights, it delivers secure retention, smooth draws, and long-lasting durability.

Important: This holster establishes retention on the mounted light, not the pistol itself. Your firearm must have one of the compatible lights installed with the #3 key for proper fit and function.
