I picked one of these up and fondled it a few days ago at one of my local fun stores. I immediately fell in love with it. It shouldered very naturally for me, seemed solidly built, it was light and felt perfectly balanced. Obviously very compact as well. I do see where mag changes would be a bit more cumbersome, but otherwise I loved the ergo. It was a very good price and came with several mags. I seriously considering it. I've read about them on a couple message boards and it definitely looks like they had some problems with the earlier models, but I've also read where several people are very happy with it. Anyone have experience with them or have an educated opinion?
