ProMag Sig Sauer P365 9mm Luger 12rd Magazine Black Oxide

The ProMag Sig Sauer P365 9mm Luger 12-round magazine gives you a practical capacity boost for one of the most popular micro-compact carry pistols on the market. If you run a P365 for self-defense or everyday carry and want more rounds on tap without going to a larger platform, this steel magazine delivers the extra firepower in a form factor that stays true to the gun's purpose. Built with heat-treated steel and finished in tough black oxide, it's designed to handle the demands of regular training and carry.

Magazine reliability is foundational to your pistol's performance, and ProMag's domestic manufacturing puts this round in the same shop as your gun's receiver. The magazine body uses heat-treated steel for durability and corrosion resistance, while the injection-molded follower and heat-treated chrome silicone spring work together to feed rounds consistently under the kind of stress that comes with defensive drills or range work. Black oxide finish resists rust and complements the P365's aesthetic without adding unnecessary bulk.

Whether you're building a backup magazine stack for training, setting up a reload station at the range, or simply want an extra magazine tucked away, a 12-rounder extends your time between reloads on the P365 platform. It's a straightforward upgrade that costs less than a trip to the range and works with the pistol you already trust.
