I handled my first A400 the other day. I'm not as impressed with it as I thought I would be. I said the same thing about the Xtrema when they first came out and it was one of the best auto's I ever owned.
The action on the one I was handling just wasn't smooth at all. The bolt was sticky and clunky. I picked up an Xtrema right next to it and it was smooth as glass. I actually tapped on the bolt of the A400 thinking it looked almost plastic. The whole gun feels like plastic to me.
The price? way over priced IMO. I wish them the best at selling them in this tough economy. I tried for years to buy the do everything gun. It never worked out. IMO, there is no do everything gun. I buy a gun now for a specific type of hunting.
