I've got a brand new 625-8. The one with the blue/white/red wood grips. Will be replacing the grips with the factory black rubber grips like those on the 629. Though SW is out of stock right now.

I'm going to replace the extractor rod and release switch with stainless steel as I don't like the blue look. I'm going with SDM thumb release stainless steel as I read you get better grip with your thumb. As I find my thumb slipping off the factory piece.

But on the extractor rod. What torque spec does that have when tightening it down? Watching this video he says there is a 45-50 inch torque spec:

I already have an inch torque wrench. And I went ahead and made a tool with a tire valve tool that I screwed a bolt into so I could put it into a torque wrench and turn it against two empty shells. With moon clips, I'll have 4 shells going into the cylinder, and have 2 shells in reverse sticking out so I have something to torque against.

I don't know what tool that guy is using on the end of his torque wrench.

I'm still deciding whether to get that Visesmith, or get a $20 vise from the hardware store and put some rubber or something on the jaws. Did try to unscrew the rod with vice grips and pieces of leather, but the vice grip chewed into rod. Didn't matter though as I'll be replacing it anyways, but don't want to damage the new rod.
