I agree 100%!!! The softer the load, the less stress and strain on the toggle system......and that is a good thing in these guns(also in the P08 Lugers) If, sometime in the future, you decide to experiment some more, there are many different std. velocity .22 cal cartridges out there for sale that might be a perfect match for your Erma. You are waaaaaaay ahead by finding a subsonic that will function reliably in your gun. Enjoy.
