It's very rare for me to decide to return a gun I just bought. This afternoon I bought a 4-5/8" Blackhawk convertible .38/.357/9mm. Getting home and cleaning off the preservative, I found both cylinders were stained in the finish. The black oxide was done when it was contaminated, or something was cooked into the cylinders during heat treat. We'll get to see how Fin Feather Fur handles it.
