The salient part of Patrick Villier's comment to me was "The Erma conversion is not all that successful".

For the $500-$600 these kits are going for these days, I'm happy to remain ignorant.

Edit: Patrick Villiers expands further on his comments on Jan Still's forum -

There are two springs in the Erma toggle; one for recoil, one for the firing pin. The Erma toggle assembly comes apart quite easily for replacing the springs; chasing them across the room can be invigorating...

Maybe Ed Tinker would be willing to try replacing his Erma 'recoil spring' with a P-38 mainspring...The Erma spring is called a 'breech-closing spring' in the Erma manual/parts breakdown...
