More on my problem M67....

First thanks for the replies.
But the ejector rod is straight and the trigger stopping half way through seems to be random on double action and never on single action.
I can go 20+ dry fires ok and then suddenly it will jam. I release the trigger and all is ok.
It's a 6K with red ramp and black rear sight - from the later 1970s.
What is going on here??
Thanks.

Most likely a timing issue, stemming from either the bolt, hand, or both.

Chances are you have just answered your own question. If you do not allow the trigger to fully recover before pulling it again it doesn't catch the hook on the cylinder stop. If you try to pull the trigger before the trigger engages the cylinder stop hook the cylinder stop stays up and prevents the cylinder from turning while the hand is trying to turn it.

It may be the gun is dirty and needs lubrication, the rebound slide spring may be too weak due to being replaced with a lighter one or being cut. Or, you may simply not be releasing the trigger fully.

By Jove, that was it. I was firing so fast that the trigger did not have time to reset and/or I was not letting the trigger fully return.
Thanks all.
