ETS S&W M&P 9mm 21-round Extended Magazine

This is a Smith and Wesson M&P9 21-round extended magazine from ETS.

Constructed with an advanced impact, chemical, and UV-resistant polymer, this aftermarket M&P 9mm extended magazine delivers superior reliability in harsh, demanding conditions.

The translucent body makes visual round counts quick and easy, while the creep-resistant design ensures the feed lips and body won't spread, even when fully loaded.

Further, a durable internal steel spring, coupled with an anti-tilt polymer follower, delivers ultra-reliable feeding, while a removable baseplate offers easy disassembly for cleaning and maintenance.

Better yet, this M&P pistol magazine is 100% American-made and is backed by ETS' lifetime warranty for superior quality and lasting field service.
