SKU: WRMESIG-0P
The Warne Mag Ext Sigp320 +0 is a magazine extension designed for the Sig Sauer P320 platform, engineered to add capacity and ergonomic control to the factory magazine assembly. This accessory is built for shooters and professionals who need extended magazine compatibility without sacrificing the baseline handling characteristics of the P320 system.
Warne manufactures precision firearm accessories with a focus on tight tolerances and functional reliability. The +0 designation on this extension indicates a zero-rise geometry, meaning the extended magazine seats and feeds from the same position as the standard magazine—critical for shooters who depend on consistent hand positioning, draw geometry, and holster compatibility. The extension increases magazine capacity while maintaining the same sight picture and grip angle that P320 operators train with daily.
This extension is favored by competitive shooters, duty-oriented personnel, and serious practice enthusiasts running the Sig P320 platform. It solves the practical problem of wanting additional ammunition on board without changing the ergonomic profile or requiring different holster accommodation. The Sig P320 has become a standard-issue platform across military and law enforcement agencies, and aftermarket magazine extensions serve both competition and field applications where ammunition capacity directly impacts shooting duration and reload frequency.
