Breech block extractor problem

You are right John, I do not plan on shooting it until I get a new breechblock. When you look at the breechblock face where the keeper steps for the extractor are with a magnifying glass you can see a small fracture. I don't think I would look very good with that embedded in my face....lol.

I have ordered a new reproduction breechblock and extractor spring. Also I ordered a recoil calibration set from Wolff. It says it comes with 3 mainsprings a 36, 38, and 40 lbs mainspring. I can experiment with these.

The thing that really bothers me is my headspace issue. If it is true (and I believe it is) DonVoigt said he measured his go/nogo gauges and they were .751/.757 My headspace right now is .776!! My chamber is cut wayyyyy too deep by almost .020 That's bad.

I thought I was ok because I was going by the SAMMI spec which said "min .754, max .776".

I bought this reproduction brand new barrel from Numerichs. It is a very nice well made barrel, they just messed up and cut the chamber too deep.

I really like the barrel and wish I could save it, but I don't think I can. Cause I like the idea of having a brand new barrel. I want a good shooter for a long time.

So now I got to try to find a new old (in good condition) 4 inch 9mm barrel that won't break the bank.

Dick, I made very sure that the extractor fit into the breechblock and extractor clearance slot in the barrel and receiver, I am a tool and die maker by trade.
