I understand how guns work pretty well, but I'm not set up to make engineering calculations like the factory is. If they decide the stock spring is still the right one with a bobbed hammer, I won't argue with that. I'm counting on them to have made the calculations and to produce a sound, reliable product.
I suspect that their "engineering calculations" only involves taking a spring from the box that came from their spring supplier and putting it into the gun...regardless if it is a spurless hammer or the standard spurred one.
