If you're gonna put rubber on the gun, take the grips off every few weeks and wipe it down under there. Rubber grips attract moisture. I have a 19-2 in near perfect condition, and while I usually go for rubber on a revolver over wood, on a nice blued S&W, the black rubber just looks awful to me. I had them on there for about 3 weeks, and when i finally switched back to the wood for appearance sake, there was moisture under the grips on the frame. Moisture will kill that nice blueing. Now i leave the wood on, and switch to the Pachmayr's when I'm going to shoot the gun.
