I've read that the SW500 is a more powerful gun. But the AE just looks like it would be fun.
If I were living in the US of A, I'd have one of those. Probably in 44 and 357 as well.

Although I have to admit that as far as 'ccw' goes, I think I would lean more towards that 357 SIG of yours.
So far, that is the one I loved best in terms of handling and recoil.
