What are the details of the geometry at the front of the frame relative to the position of the locking lever and the receiver lug?
If this ends setting the receiver too far back with reference to the place where the toggle contacts the receiver ears the timing of the action could be changed. it's subtle, but also critical to proper function.

Marc,
The hump is part of the grip frame, in which the receiver moves!
It seems to me that the dimensional relationships of all the top end's working components are maintained no matter what combination of receiver and frame. I think the difference is approximately 0.10", and it all takes place ahead of the chamber, right behind the barrel flange; so, it does not affect anything else. Remember seeing pics posted of guns that were the opposite, and had the snouts of their frames ground back to be flush with the barrels?

This one looks good. Luckily, the Erfurt frame is new model and is flush with the upper!
