The ProMag SMI40 is a 10-round 9mm magazine built for the Smith & Wesson M&P Shield EZ, a compact, single-stack pistol that's earned a solid following among shooters who value ergonomics and straightforward operation. This blued steel magazine delivers reliable feeding in a firearms platform designed around accessible controls and shootability—whether you're training at the range, carrying for personal protection, or testing your fundamentals with a gun that doesn't demand a kung-fu grip to operate.
ProMag has built a reputation manufacturing aftermarket magazines for common defensive and sporting platforms, and this SMI40 follows that playbook: a straightforward steel construction in classic blued finish that matches the aesthetics of the Shield EZ itself. Ten rounds gives you useful capacity in a magazine that maintains the Shield EZ's balance and concealability—you're not buying this for a competition rig, but for a practical reload that fits the gun's mission.
If you run a Shield EZ, having a spare magazine or two on hand is just common sense. A dedicated magazine lets you practice reloads, keep a staged reload in a truck or bag, or simply have a backup if your factory magazine needs service. ProMag's approach here is no-frills: make the round count and the fit reliable, keep the price accessible, and let shooters get to work.
