Interesting that this subject just came up. I recently picked up a Safety Speed holster for a 6" K frame. Black basketweave. I have been looking for one for some time now, just as an example of a very unique holster. Mine is the pop open clamshell. I did a little research too, and, apparently, they are long gone.
Its an amazing holster. Heavy as a brick. Now I'm looking for a 6" K38 to put in it. It was a tough sell to the wife..
"You bought that old holster?"
"Do you have agun to fit it?"
"Even for you, does that strike you as a little wierd?"
Such is life....
