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

The ProMag SMIA16 is a 13-round extended detachable magazine built for the Smith & Wesson M&P .45 ACP pistol. Designed as an upgrade or spare, this magazine adds three rounds over the standard factory flush-fit mag, giving you more firepower between reloads during range sessions and competition.

Constructed from heat-treated steel with a blued (oxide) finish for strength and corrosion resistance, the SMIA16 is engineered to feed reliably and seat properly in your M&P .45 ACP. The robust all-steel body shrugs off the abuse of regular use while maintaining smooth slide-lock function. This is a standard series replacement magazine, made in the USA by ProMag, and is specifically designed for the full-size S&W M&P45 .45 ACP pistol. It is not compatible with the M&P 9mm, M&P Shield, or other M&P variants chambered in different calibers.
