Soo.. issue: Fires on action release

The geometry of how the round is held in the mag changes as the round moves forward, and can impart a bit too much "rise" to the front end at about the point it encounters the feed ramp. The block does not ride over the rim in this case, just squeezes it because the front did not hit the chamber vertically centered enough to be guided in. The nose of the round can also catch on top of the chamber.

Changing main springs is not that bad a chore if you have one of Jim Solomon's tools, and have watched a YouTube or two to see how it is done.

I had exactly the same problem and followed ithacaartist's advice, got a new spring from Lugerdoc which solved the issue completely. Many,many thanks.
