How can I tell if I need a new mainspring?

Unspellable, thank you for the truly excellent information about the hows and whys of the Luger recoil springs--I made a hardcopy of your post and will keep it in my Luger file. I have installed new Wolfe recoil springs in my 1917 Erfurt and 1923 Commercial, and I would say that although it can be accomplished, it is not a job for the faint of heart. I noticed some slight peening on the ramps of my Erfurt, and Thor pointed out to me that this was a possible indication of a weak spring. I installed the regular power Wolfe recoil spring, and that old Erfurt fought me every step of the way! I put the reduced power spring in my '23 (it's a .30), and that made the job somewhat easier. Thanks again for the great explanation.
