SKB,

I wanted to go for the gunsmith's school this year. Unfortunately my wife wants to vacation somewhere else.
RWTF and Chuck H, I need a firing pin bushing.
It is a metric, M7 with .75 pitch outside thread. I thought of filing it out of an socket set screw after drilling the pin hole, but my local store did not have it...
I'll look around at Brownell's or MidwayUSA. Maybe MSC will have something close.
And that's only one thing...
