RVD,

First off I'd choose a Thompson over either. Second off a muzzle velocity of 285 m/s isn't uncommon for .45. Mind you both the UMP and Thompson are using the .45. So similar performance in regards to rounds shouldn't be shocking. That said while the MP7 has the higher velocity round, generally speaking the.45 still hits with more energy. In common parlance its the more powerfull round.
