The ShapeShift® Shell for Sig Sauer pistols is designed to give you unmatched flexibility within the ShapeShift® Modular Holster System by Alien Gear. Whether you're carrying a Sig Sauer P320, P365, P229, or P365XL, this shell allows you to quickly transition between carry methods without needing a full new holster—making it ideal for users who rotate firearms or adapt their setup for different environments.
Each kit includes a precision-molded holster shell engineered to match the exact dimensions of your specific Sig Sauer model, an adjustable passive retention unit, a rotating adapter, and a full hardware parts pack. With just one shell, you can move seamlessly between IWB, OWB, appendix, shoulder, backpack, or drop leg platforms—giving you the power to customize your carry system on the fly.
Constructed from a durable, heat- and abrasion-resistant polymer, the Shift Shell is built to withstand daily use while maintaining a low-profile footprint for excellent concealability.
NOTE: This shell does not fit co-witness slides (e.g., optics-ready models with raised 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.
