Here is my 642-1. Those blue stocks are Blue Lava from Hogue.
The knife is a very sharp Piranha. The little black speed scabbard
is by Chic Gaylord. The cheezy belt is from Uncle Mike, because
it's the only one I have that will fit the little bitty belt loop that
Gaylord used in the 1960s.
I forgot about my 686-1. It's bead blasted and I think it was done at the factory. I have a 4 inch CS-1 barrel and it has the same finish. I do plan to install it at some point. I prefer the black ramp sight for most of the shooting I do
