ProMag Industries, Magazine, 40 S&W, 15 Rounds (Black)

ProMag Industries Magazine — .40 S&W, 15 Rounds (Fits S&W M&P-40) — Steel, Blued Finish

Reliable spare capacity. Factory-fit replacement for M&P-40 platforms.

This ProMag Industries 15-round magazine is a steel-bodied spare built to fit Smith & Wesson M&P-40 pistols. Finished in durable blued coating and assembled with a dependable spring and follower, it gives shooters an easy drop-in option for extra on-gun capacity during range sessions or as a serviceable replacement mag for training and daily use.

Key Features

• Caliber / Capacity: .40 S&W — 15 rounds.

• Fit / Compatibility: Designed to fit S&W M&P-40 pistols.

• Construction: Steel body with corrosion-resistant blued finish for durability and low profile.

• Follower & Spring: Polymer follower and heat-treated spring for smooth feeding and consistent tension.

• Baseplate: Flush-profile steel or steel/poly baseplate for secure indexing and storage.

• Packaging: Sold individually unless otherwise specified — check listing for pack quantities.

Why It Stands Out

A straightforward, affordable steel magazine that mirrors factory geometry for reliable lockup and feeding in M&P-40 pistols. The blued finish provides a classic look while the robust steel body resists deformation under heavy use—making it a durable choice for regular range work and spare-mag rotation.

Perfect For

• S&W M&P-40 owners needing a reliable spare or replacement magazine

• Range regulars and instructors running high-round drills

• Shooters who prefer steel magazines for durability and feed-lip stability

• Armorers and shops stocking OEM-fit magazines for service and repairs
