I have a stainless compact which I've routinely carried for around 2 years. If the hoster wear on the parts that are still HE finished (sights, slide release) are any idication of what the slide would look like, then I'm certainly glad I got the stainless. If you're not planning to carry it, or at least not often, either will prolly do. If you are going to carry and would like it to continue to look new, get the stainless.
