dumb pistol question

Doesn't matter. The amount of energy in a striker spring is pretty low, the amount of tension when 'cocked' is even lower.
If you really worry about it, just remove the slide from the frame. Fire on the snap cap, remove the slide, remove the barrel, remove snap cap, and put all the parts into a case to prevent part loss.
I'd be more worried about losing parts than about striker springs though.
