The ProMag SIGA18 9mm Luger 20-Round Blued Steel Magazine delivers extended capacity for Sig Sauer P365 and P365 XL pistols in a durable, duty-ready package. Constructed from heat-treated steel with a corrosion-resistant blued finish, this double-stack magazine is engineered for consistent feeding and dependable performance shot after shot.
This extended magazine is ideal for shooters who want more time on the range between reloads or prefer additional capacity for everyday carry. A precision-wound chrome silicon spring and injection-molded follower promote smooth cycling and reliable lockback, while the contoured basepad helps maintain a secure grip during reloads. Whether you are training, competing, or spending a long day at the range, the SIGA18 complements the compact P365 platform and reflects ProMag’s focus on practical performance and reliability.
