Some good comments here: FN Five Seven review policelink
I actually thought you were talking about the Smith and Wesson Model 57. It's in 41 magnum caliber. The old pinned and recessed Smiths truly can't be beat. That's one caliber/gun I wouldn't mind gearing up to reload. ;)
Good talking to you. Watch your tail, cowboy.
