BTW No one's mentioned it yet but if you can't find P90 specific mags pouches UMP pouches will work in a pinch. As far as the kit goes, I don't really care for P90's but like people say "ride your own ride".
I'd also say to shy away from Elite Force unless you're using them more as show pieces than wanting to use them a lot. Personally I rarely use my sidearm and it's used more as a showpiece than anything. That said my play style may be totally different from other people's and you may find yourself using your pistol a lot more than I do. Maybe look at getting a KJW 1911 if you can afford it.
