I've seen both. It doesn't seem to matter how old the gun is. Some older ones are still blue, some newer ones relatively speaking are turning plum.

I understand it is the continued oxidation, but why do some continue to oxidize and others do not or do so much more slowly?

Is it a different process, different solution, different metals? Curious.

There are theories that it all has to do with the alloy used in the investment casting of the frame.  You'll notice that it only happens in the frame - never in the barrel shroud or side plate, because the frame is the only part that is investment cast.

I am not an expert, just passing on what I have read and observed. Some say that the silicon in the mold used to cast the frame interacts with  the alloy. I'm speculating that different molds might have different amounts of silica in the ceramic or over repeated use leaches it out. Old Rugers and other firearms also turm plum. Trigger groups on lg. frames also barney. It is very common on 357 max. frames, especially early ones. Even guns that look very blue show a little different hue in sunlight.

If you go over to the ruger forum they have some back ground on the subject as to why the old rugers turned plumb colored.occasion

There were a couple possible explanations depending on the methods and/or solutions on the Ruger forum. I've seen some of this in a couple of my guns.

I have a "Porkchop" DW, and the frame is blue, and the barrel shroud is purple.  Looks odd, but it is what it is ...

Alonzo, that is very unusual.It is almost always the other way around. Plum frame and blue shroud and sideplate. Some folks love what we call " Barney ie; the purple dinosaur." I am sure that any number of members would swap with you in a heartbeat. You could have an all blue gun and they would have a mostly plum one. If you have a plum sideplate too you could write your own ticket.

That plum color kind of hints toward its age.  I have DW pistols that have been stored in their original boxes that or 30 yrs old and have never been shot or exposed to sun light but for a moment [stored in a safe]. And you can see a little Barney color to the frame. I said this to say, "I don't think sun light causes this to much." It must be a chemical/alloy break down.

The reason is really simple........and then not........for those without metallurgy degrees or in the injection mold industry.........

Investment castings are very porous. When done well, and then heat treated properly and (more importantly) timely before bluing or plating, exhibit these traits. Note: S&W forge their frames, and rust is a CONSTANT problem, even on the "stainless" weapons. 

Personally, I LIKE the patina/purple traits of an aged weapon. It's built with a purpose and not rusted away meaning the owner DID take care of it, although the MFR did not understand what time/use would do to that kind of steel and/or treatment of it. The blueing salts, etc, are doing their job under the surface, in other words.

I have a few "Liberty" model Rugers from my Pops that exhibit the same trait, that, before his death I had given him one of every Xmas, before his death. Now I have them.

The "purple" color is simply rust, trying to win, under the blue. It's nothing to worry about, however, keep it oiled and wiped down. A badge of honor for age, kinda like my white hair...........

An explanation I've never heard, but very logical to an old rude dawg like myself.

I'd buy into that theory. smile

DW's are definitely not the only manufacturer to have this happen, I have seen plenty of Rugers & other brands afflicted. It's interesting to me that it's so "hit-n-miss" in each brand, no matter which brand you look at.

I have a model 12 that is a black as night and I have a NIB never fired  Norwich 44 that has a Barney cylinder so age doesn't seem to be that big of a factor.

Anything worth doing is worth doing well.

Both of my 15-2's show slight plumb color just under the crane in front of the trigger guard. Both made in 77-78. 2-DANS-e.jpgImage Enlarger

WD40 is the culprit ....... guys would store blued guns with WD40 , long term it would react with some or all parts of the gun, rifles included

Welcome sideoiler.  Your reference to WD40 would only make sense if the whole gun was subject to Barney-ing.  That's not the case with DW's.
