Well, it depends on the owners. Some people will jump on the DM5 bandwagon and say "the DM4s are old and I wouldn't be caught dead with one". Other will say that they spent $1200 on a gun so they're going to stick with that gun. It all depends on the person. If you want a DM4, buy one. But if you want to wait untill Cup to buy a DM5, you can do that too. Its up to you and how nit picky you are about guns. If you are going to buy a DM4 and say "DM4s are better then DM5 because of this and this.." just to help you sleep at night, wait for the DM5.
