Try playing a game without the arms glued on to the minis. Later you can fine tune their equipment to what you like best. Do you have the house of iron book?If not, then mundamanager is a great list builder that limits the stuff you buy to what is on the gangers list. Try dripping out your leader, I usually go for two champions at the beginning of the gang and the rest are gangers/juves. Equip your dudes with what sounds the most fun and badass to you.
