- MP7's Official page (link)
- You will find three variants of MP7 (I'm not taking into account the classic MP7 model):
- MP7A1: The MP7 as we know it, with the folding front grip.
- MP7A2: A variant without the folding front grip, replaced by a picatinny rail.
- MP7 SP: Semi-Auto only, for police units.
