Bub, our range officer has a similar problem. He rotted the finish off a stainless/nickel Smith Airweight twice; the second time he sent it off to Smith for refinishing, they shipped him back an all-stainless one and said 'don't call us; we'll call you".
If you really have that much trouble, you might either wait for the Ruger one, or get current production and investigate having the slide hardchromed. Done right, hardchrome is incredibly durable (more so than stainless). My counsel would be to hardchrome the slide only; even magazines could be kept wiped; once inside the grip, it shouldn't matter.
Do consider an LCP. I'm a longtime J-frame guy, but the little Ruger is just so much easier to hide that it isn't even a contest.
