The ShapeShift® 4.0 IWB Holster for Sig Sauer delivers premium comfort and security for everyday concealed carry of your Sig pistol. Whether you carry a P320, P365, or P238, this holster provides a secure, close-to-body fit that’s optimized for both casual wear and all-day use.
This holster includes adjustable cant and ride height, letting you fine-tune the draw angle and depth for your preferred setup. A custom-molded retention shell fully encloses the trigger guard for added safety, while the slim profile reduces printing for deep concealment. As part of the ShapeShift® Modular Holster System, it’s also compatible with a wide range of carry configurations using the same Sig shell.
NOTE: Does not fit co-witness slides or suppressor-height sights.
Confirm firearm manufacturer and model, generation, barrel length, dominant hand, optic, weapon light and mounting interface before purchase. Only the configuration selected on this page is included.
