josp, thanks. I will do that, I know their not perfect and actually want one that is kind of scratched up so I don't have to worry about it.

I have an old S&W screw driver that use to come with them years ago that I will be using. I don't have any of the gunsmithing bits or drivers. Don't really want to bugger up the screws but guess it really won't matter on this one.

I have a couple of the Buds gunshop model 10 Victoria police trade in revolvers and kind of messed their screws up using a regular screwdriver so I'll try the old S&W one. The model 10's were really clean and didn't require much cleaning like some of the 640-1's do.

Thanks again
