To store cocked or uncocked?

I don't believe in dry firing any Parker, regardless of the little tag they printed. The hammer comes to a screeching halt somewhere, and I'd rather it get some cushioning from a pair of snap-caps than the frame pocket in front of the hammer.

From a practical point, I don't believe anyone has ever proven that Parker hammerless coil springs suffer significantly from long-term compression. Do you jack up your car and put it on blocks when you go on vacation?

From a metallurgical standpoint, there is nothing taking place that changes the ductility of the spring material.
The other reason I don't think it matters, in the case of an ejector gun is that the ejector hammers also remain compressed, even if you dry fire the hammers onto a pair of snap-caps. I have never heard of anyone storing their hammerless Parkers in a dry fired, and opened (ejectors fired) position
