Not sure if it makes sense or not.......interesting.
Honestly, what I would do is ask if they would install the plunger from the new MA1. The nose of the new plunger is rounded, eliminating any chance of incorrect orientation, and - IMHO - reducing excess friction between the claw & plunger.
I have had no extraction issues or erratic brass in my M9 or S9 since break-in; they eject just fine. However, the new design just sounds better to me, and I plan on purchasing a new assembly for both pistols once they are easily available.
Perhaps they'd be willing to install the new style for you, which should eliminate your problems.
I'm a little shocked that the tech would not suggest this on his own......
