This has probably been discussed but my search abilities aren't working tonight. Why do some of the DW frames turn purple? I know it's blueing going to patina but why only the frame? I've seen some/most with the frame turned but the side plate not. Just puzzles me is all.
Thanks, Pecos

The frames on Dan Wesson revolvers are an investment casting. One or some of the elements in the alloy used to make the casting react with the bluing over time and cause it to turn purple. The shrouds are cold rolled and I believe the side plates are machined from stock - that's why you don't see the purple tint on those parts. There have been previous discussions regarding what in the alloy is causing the bluing to turn color but I am not sure if it has ever been documented in a controlled environment. IT does appear that the composition of the base varied from lot to lot - that's why you see it on some and not on all frames.

My T/C pistol turned that Barney color too. Perhaps it has the same casting. I sent it to Smith&Wesson who owns T/C now, for a repair. They repaired and blued it for me at no charge.

Thanks, Harly. I didn't know those were investment castings. That would explain the change as Ruger's Blackhawks used to do the same thing.

Even my prized Seville in .41 Mag has the Barney effect on the grip frame and ejector rod housing. I think it gives the guns a certain character.

IHMSA,
That is interesting. My USA 41 is also a bit on the Barney side, much like a DAN. I had never seen the Barney effect other than Dans and USA revolvers. Hmmmm..

I've seen the Barney effect on lots of brands, from photos on other forums & auction sites. Rugers, T/C's, Smiths (rarely), Colt (rarely), Charter Arms, & Taurus are some that come to mind. At this point, I don't think any gun company is immune.
