Key Features
Construction & Durability
The ProMag SIGA4 magazine for the Sig Sauer P226 is engineered for consistent operational reliability. Its body is constructed from heat-treated blued steel, a material selected for its structural integrity and resistance to corrosion and wear under strenuous use. Internally, a heat-treated chrome silicon wire spring provides consistent tension, mitigating feeding malfunctions, while the injection-molded follower is designed for smooth, unobstructed cartridge presentation to the feed ramps. This robust assembly ensures enduring performance in demanding environments.
Capacity & Compatibility
This magazine offers an extended 20-round capacity, optimizing ammunition availability for training exercises, competitive shooting, or duty applications where reduced reload cycles are advantageous. The SIGA4 is specifically designed for the Sig Sauer P226 platform and is compatible with both .40 S&W and .357 Sig calibers, providing versatility for operators utilizing either cartridge.
