ProMag S&W M&P-40 Double Stack Magazine .40 S&W Blued Steel 25/rd

The ProMag S&W M&P-40 Double Stack Magazine .40 S&W Blued Steel 25-round capacity is designed for use with the Smith & Wesson M&P-40 platform, making it suitable for both law enforcement and civilian shooters. This magazine allows users to extend their firearm's operational capacity to 25 rounds, ensuring reliable feed cycles during high-volume training, duty rotation, or competition scenarios.

Constructed from blued steel with a double-stack design, this magazine maximizes round capacity while maintaining a shootable ergonomic profile and reliable spring tension. The 25-round configuration ensures consistent chambering and positive feeding of .40 S&W ammunition without binding or stovepipes. The blued steel finish resists corrosion during extended storage and field conditions, while the robust follower and witness holes allow for easy confirmation of remaining ammunition count.

M&P-40 users benefit most from carrying multiple ProMag magazines on duty belts, range bags, or in vehicle kits, as the double-stack geometry fits standard M&P-40 magazine pouches without requiring modifications. The 25-round capacity provides ample ammunition for extended shooting sessions, making it an essential accessory for serious shooters.
