Personally I'd go with the .44. It sounds like you just want something to reload and shoot for fun. If you really want the .357 just wait a few weeks, they will turn up. I'm the same way, when I want something I want it now, but if you just wait you will get what you really want. That probably doesn't help much but thats what id do.
There is no such thing as a stupid question, only stupid people.
