Forgot to put advice in my post. Yes, I'd pick the .357 also. If you ever plan on selling the gun, it'll bring a premium that way. If, however, you can save the money upfront on the gun that could also be a consideration.
Handgun: I've seen two 357's that you couldnt' chamber a magnum in for the reasons I've stated above. Proper care most-often prevents this condition, but I wasn't making a suggestion, just putting forward why other people make their decisions. I think "Magnum-phobia" is the main reason though.
