The CO₂-powered T4E version is the corresponding high-end training gun. Authentic dimensions and functional elements, plus a convincing recoil, provide for extremely realistic handling even without live ammunition. The M&P9 M2.0 T4E fires .43-caliber roundball T4E ammunition. It shares many features with the original: trigger safety, Picatinny rail and adjustable sights. The optional Quick Piercing Magazine provides an instant operational readiness. The LE version has additional conspicuous blue elements to show that it is a training weapon.
