ProMag SMIA16 S&W M&P 45 ACP 13-Round Extended Magazine Blued

The ProMag SMIA16 extends your Smith & Wesson M&P 45 ACP capacity to 13 rounds while maintaining reliable feeding and function. This extended magazine provides additional firepower for competitive shooting, training, and tactical applications where maximum capacity matters.

What Makes This Different

Unlike standard 10-round M&P magazines, the SMIA16 adds three additional rounds through an extended baseplate design. The blued steel construction provides corrosion resistance and durability that polymer alternatives cannot match. Heat-treated steel components ensure consistent spring tension and feeding reliability through thousands of loading cycles.

Key Features

• 13-round capacity - 30% more ammunition than standard magazines
• Blued steel construction with anti-corrosion finish
• Heat-treated steel spring maintains tension under heavy use
• Extended baseplate provides positive grip during reloads
• Drop-free design ensures smooth magazine changes
• Compatible with all Smith & Wesson M&P 45 ACP pistols
• Witness holes allow visual ammunition count verification

The SMIA13 performs consistently across temperature extremes and maintains feeding reliability with various 45 ACP ammunition weights. Competition shooters benefit from the reduced reload frequency during extended courses of fire. The extended length provides improved grip purchase during tactical reloads while the steel construction withstands repeated drops on concrete and gravel surfaces.
