M&P is the Smith & Wesson abbreviation for Military & Police. This is the designation reserved for guns used by tactical officers and others for self-defense. The M&P9 M2.0 is a good example. The CO₂-powered T4E version is the corresponding high-end training gun. Police and security services can use it for practicing routine operations. 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. Suitable for all T4E Roundballs in cal. .43.
