Sig Sauer P365 / P365 XL IWB Holster
This Inside the Waistband (IWB) holster for the Sig Sauer P365 and P365 XL is precision vacuum-formed using a CAD-based mold modeled from the actual firearm. Each holster is designed for secure concealed carry, consistent retention, and everyday comfort.
Every holster is formed, trimmed, and folded in-house, then tested with the real pistol to ensure proper fit, function, and retention out of the box.
