Transform your Sig Sauer P320 into a modern X-Series platform with this purpose-built grip module assembly. Designed for shooters who demand modularity and precision, this medium-sized grip accepts your existing P320 firing control unit and converts it into a full-size X-Series pistol.
This grip module does not include the extended magwell or internal weight found on some X-Series variants. Use magazines with the SIG Mark baseplate—magazines marked "SIG SAUER" are not compatible with this module. Requires compatible P320 slide and barrel assemblies for your chosen caliber.
Sig's X-Series platform represents the evolution of the P320 modular system. This grip module delivers the refined ergonomics and performance that modern shooters expect, whether you're training at the range or carrying professionally.
