David,
Thanks for the info, these guns are finnicky (to say the least) and it seems like you have the patience of Job tinkering with it. One of the major problems with these guns seems to be that the toggle action doesn't really serve much of a purpose, they incorporated it just for looks and getting the proper balance between the springs seems to be more a matter of luck than engineering.
I don't know how many hours I have spent fooling with my LA22 and I was about to put it in a dark corner of the safe to forever rest in peace, but I might pick it up again and try the magazine mods. Can't let the gun win...
