Was able to 'look' at a Sub 2000 9mm at one of the local shops. Really different from the earlier model. Noticed the bolt hold open on the handle, a slot so you can move the op handle and catch it in the open position. All plastic. The barrel pivot is plastic too. Not quite sure how the barrel is held in place, but looks like a good rifle. For the price (had 319 on it), not bad. I'll wait for them to drop or when they get more common. But why do I need another 'sub rifle'? I've got the Sub 40....
The dealer was telling me that the older Sub series was replaced because of feeding problems, jams so on...... I don't beleive him. Usually that means your ammo might not be hot enough. (This one place has a guy that exagerates a lot....) I think it's because it cost Kel Tec too much money to make the original Sub. Suggested retail was near 700....
Over all, the new one is a good looking rifle.
