The Sig Sauer 8901258 Tactical IWB Holster is a versatile inside-the-waistband carry solution purpose-built for the P365-XMACRO. Designed with appendix carry as the starting point but equally at home in a strong-side position, this right-handed holster puts comfort and adjustability in your hands. Its modular design means you're not locked into one carry style—swap components to shift positions without buying new gear.
The standout feature is the concealment strut, engineered to press the gun's grip snugly against your body while the built-in height adjustment lets you dial in the ride height to match your belt. The strut isn't permanent; the holster ships with all hardware to remove it entirely if you prefer appendix-free carry. Underneath, the trigger guard screws let you fine-tune retention tension to your preference. The metal belt clip is equally customizable: loosen a couple of screws, adjust the cant and ride height, and you've repositioned the entire holster without tools beyond what's already in your kit.
This IWB holster is factory-cut for the ROMEOZero optic, so you can run it with or without the red dot—no modifications needed. The Kydex wing supporting the belt clip is shaped to flex naturally during carry, reducing pressure points and hot spots during extended wear. Black Kydex construction is durable, cleanable, and requires zero break-in.
