Why Choose This Magazine
Polymer magazines have proven themselves in both competition and duty use. The extended capacity gives you more rounds downrange between reloads—valuable whether you're training, competing, or practicing defensive scenarios. The witness holes eliminate guesswork about remaining ammunition.
ETS magazines are known for consistent performance and longevity. The Carbon Smoke finish provides a professional appearance while resisting wear.
Practical Considerations
This extended magazine will protrude noticeably from your M&P 9mm, which affects concealment but improves handling and reload speed. It's an excellent choice for range training, competition, and home defense applications where concealment is not a concern.
