Sig Sauer P365 380 ACP Caliber Exchange Kit 3.1" 10+1 Night Sights

The Sig Sauer P365 Caliber Exchange Kit transforms any P365 platform pistol into a 380 ACP configuration, delivering reduced recoil and enhanced shootability without sacrificing the compact carry profile. This complete conversion system includes a black nitride-finished slide, barrel, and 10-round magazine, maintaining the P365's renowned reliability in a milder shooting cartridge.

What Makes This Different

Unlike aftermarket conversion options, this factory-engineered system maintains Sig Sauer's manufacturing tolerances and quality standards. The black nitride coating provides superior corrosion resistance compared to standard bluing, while the included SigLite night sights ensure target acquisition in low-light conditions. Installation requires no permanent modifications to the host pistol, allowing users to switch between calibers as needed.
