The Promag Sig Sauer P365 Handgun Magazine in 9mm Luger, model SIG-A21, is a 20-round magazine designed specifically for the Sig Sauer P365 9mm pistol. This magazine is ideal for operators and serious shooters seeking increased firepower and extended range time between reloads, making it suitable for various shooting scenarios.

Constructed from heat-treated steel with a black oxide finish, this magazine is built to resist corrosion and wear under field conditions.

Law enforcement, armed civilians, and range competitors using the P365 platform will benefit from the 20-round capacity, particularly in multi-stage courses of fire or training sessions where minimizing reloads allows for greater focus on marksmanship and technique. This magazine meets domestic production standards and supports local supply chains, making it a reliable choice for those who prioritize quality and performance.
