Hi Karl, the problem breechblock, shows considerable wear at the bottom of the lip on the breechblock face? where it picks up the next round when loading. Nothing that would alarm one to a problem, just no sharp edges anymore? It was a used breechblock when I first installed it, and I don't know the amount of wear or damage that was present initially? And, I was blissfully unaware of any difference that mattered? But, the extraction and ejection was fair, or normal when I started the testing cycle, and degenerated from there. I must say though, I have never, to my recollection, had a Luger work like it does now? I'm not really sure what enabled the now powerful ejection cycle... The issue may be more prevalent in shooters that some one might have polished the breech face to facilitate loading or modified it to solve an unrelated issue? If I learn more, I will report, best to you, til...lat'r.....GT
I dug out the old B'Block and the edge inside the front breech face is still pretty sharp? It leads me to believe the "cure" part of the new B'Block might not be in the front part???... I will look deeper as time permits...
