Last Saturday, I had one and only one half cock during a sixth range session in a row. I was shooting with some other people and at about 150 rounds (all good up to that point), I said, “Now I’m gonna try to induce half cock.”
So I did doubles as fast as I could and sure enough, I got one to happen.
This is with an Extreme Engineering disconnector in the Prodigy. Also, I had reduced over-cock to a small amount. These two changes didn’t hurt anything.
I think there is a timing thing going on, and the recoil spring is the main driver of slide cycle timing, so that’s why I’m thinking about it. But I won’t be surprised if this isn’t solvable with a different spring weight.
Feeding, extraction and ejection remain 100% reliable.
