    When did Krieghoff change from the extractor with the retaining screw to the spring loaded ball setup?

    Thanks,

    Probably just to make it easier and quicker to remove for cleaning. No tools needed ---- just give them a little tap with a small block of wood or something similar to drive them past the retaining ball.

    My question was when, not why. I agree with your answer as to why.

    Also, occasionally the small screws would back out just a little making the gun difficult to close. I remember the change but I can't put it in a time frame. Things that happen in the past seem to get jumbled up in my mind.

    Pat is correct - those screws backing out scored a lot of receiver interior walls.

    I was also told (by Dieter Krieghoff, I believe) that screw-type ejectors were prone to breakage across the screw hole, so they changed the design. In fact, screw-type ejectors were under a Krieghoff lifetime replacement policy at one time and still may be. I had one break on one of my Model 32s and it did break across the hole.

    The same thing happened with Model 32 hammers. When they were drilled for a release sear to be installed, they were weakened and often broke across that hole. K-80s used those hammers at first but the second-design hammer had the release sear forged as a part of the hammer.

    Look at that extractor slot--- if you notice it would take several machining operations with the old one and only one it looks like with the new one.

    I hazard it was a combination of factors to change the extractor but I have never had an old one break but have seen a new one break

    Its also easier to clean the old ones because you dont have to worry about that little spring and ball going flying

    When- is hard to say becaue barrels could have been made and then not serial numbered or put on a gun even for quite awhile

    I think I have seen a bunch as late as 23XXX
