The ETS Group SW9MP17 is a 17-round 9mm magazine built for Smith & Wesson M&P full-size pistols. If you're running an M&P in 9mm and need a reliable, affordable way to load more rounds downrange, this clear polymer magazine delivers the capacity without breaking the bank. ETS polymer magazines have become a go-to choice for shooters who want function that doesn't quit, whether you're at the range, in competition, or training hard.

The translucent body is one of the standout features—you can glance down and instantly verify your ammo count and ammunition type without removing the mag from your pouch or carrier. The ergonomic floor plate is designed to be easy to grab and strip from a mag pouch, and the base plate disassembles with ETS's purpose-built design in mind. That means cleaning, maintenance, and spring replacement are straightforward tasks. The interchangeable base plate also works across ETS's 9mm double-stack lineup, giving you flexibility if you're building out a mag system. (Note: this magazine is not compatible with the Shield variant.)

ETS engineered these magazines from advanced polymer that resists impact, chemicals, and the kind of environmental abuse that ruins lesser mags. They won't crack or shatter when dropped, stay stable in extreme heat and cold without becoming brittle, and resist UV damage if you're storing them or carrying outdoors. The feed lips and body won't creep or spread even under long-term storage at full capacity—important if you rotate mags in and out regularly. If a problem ever crops up, ETS backs the mag with a lifetime warranty.
