I think that in a full auto, SBR platform then sure, its got a place...just as much as the mp5 does. As far as semi auto I would prefer a glock 17 over an m4 9mm. The reason being is that the 9mm m4 would be suited for CQB type situations. Theres no real fire power advantage with the m4 (as compared with a g17 using a g18 magazine.) For what little benefit the buttstock will be to you, the added barrel length will hurt you more as far as retention goes. The glock would be far lighter, faster and easier to manuever in real tight environments. Sure, the m4s will probably beat the g17 in the accuracy department, but when you're working in distances that are common to one's house for instance, distances generally are within 10 yards or closer.

A semi auto m4 in 5.56 is a different story however.
