I received a shipping label from S&W and sent it back today. I decided that, after weighing all the options, I want a certification that it is OK. This is more for the collector value and future owners peace of mind than anything else.

I did a lot of research and made a lot of calls without being able to make any conclusions.

The gun wouldn't chamber a .44 magnum round, so it doesn't seem, per Mr. Jinks, that is the problem.

Before I shipped the gun I noticed an "M" inside a triangle on the bottom side of the grip frame. I'm sure as in the case of the "F" on the back of the cylinder this doesn't mean anything either, like maybe "magnaflux"?

I'll let everyone know the results...
