FWIW, I bought a Beretta tomcat about 2 years ago. Despite living in a dry climate (SoCal), the blued parts of that gun were covered with rust very quickly. Nothing like that happened to any of my other guns, or, indeed, to any other metal thing I own. Just something to keep in mind.
Thing is, I don't think you want to put a whole lot of rounds thru it.....and it sure makes my hand tired after about 10 clips (but that's just to get used to the feel of it, so's all I really need)....
But I do like that Tomcat.
