ProMag SMIA18 Standard 40 S&W 15-Rd Blued Steel Pistol Magazine for S&W SD - Except VE Variant

The ProMag SMIA18 is a standard-capacity 15-round replacement magazine purpose-built for the Smith & Wesson SD40 series. Designed for reliable feeding in .40 S&W duty and self-defense pistols, this drop-in spare is a cost-effective replacement for a worn factory magazine or a smart second mag to keep loaded and ready.

The magazine body is constructed of heat-treated steel and finished in a protective black oxide (blued) coating for corrosion resistance and long service life. An injection-molded polymer follower and quality wound spring sit inside the body to deliver smooth, consistent feeding round after round.

This magazine fits the S&W SD platform in .40 S&W, with one important note: it is not compatible with the VE variant of the SD40. Always confirm your pistol's model before installation.

Made in the USA by ProMag Industries, the SMIA18 is a trusted aftermarket choice for SD40 owners looking to round out their magazine complement.
