mainspring balancing act!

[G.T.]

Hi to all, I agree with gunbugs and would rather mess with the mainsprings rather then the higher velocity ammo. When everthing is as right as I can make it, the Luger will run on the WW White box without any issues. Problem is, sometimes the issues affecting the function of the toggle assembly are really hard to determine. When trying "stronger" ammo and the problems go away, it at least shows you that the geometry is pretty close to correct. Interesting quest! Best to all, til....lat'r....
