“Stainless” doesn’t mean “won’t rust”.

“Stainless” doesn’t mean “won’t rust”.

I hear the advice all the time: “buy a stainless gun, because they won’t rust.” This kind of comment is what prompted General Norman Schwarzkopf to say “bovine scatology!”

Yes, stainless will in fact rust under the right conditions. What are those conditions? Generally, if you get moisture trapped in a place where it doesn’t evaporate normally (say, under a grip panel or inside the action), you have a situation that is ideal for corrosion. The situation is worse in very corrosive (salt water, perspiration) or very humid conditions.

That’s not the only thing; even if the frame of your gun is stainless, there will be some parts in the action that aren’t, or are made of a much less resistant stainless. It’s not unusual to find springs, some screws, cylinder parts, and more that are made of plain carbon steel. These are just as susceptible to rust as they would be in a blued gun.

I see quite a number of stainless guns that have corrosion. One commonality of those I’ve encountered is that, since the rust is usually hidden (and less likely to be found because of the belief that stainless “doesn’t rust) it usually does more damage. Stainless corrosion tends to be deeper, leaving surface pitting that is more serious than it might be on a blued gun.

If you live in a harsh environment – near the ocean, or in a very humid climate – or if you perspire heavily, you should treat your stainless gun more like a blued equivalent. Take the grips off every time you clean the gun and look for any signs of corrosion; use gun oil on the entire surface of the gun; clean the bore immediately after shooting; take the sideplate off occasionally and lubricate the interior; and always remember that the term is “stainLESS”, not “stainFREE”!
