toggles hitting hard on frame

[c141b]

I have been reading about how hard a toggle should hit the frame so I tried the tape method. I have 2 lugers; the first set of 3 pictures is a S42 luger. I was shooting Winchester white box 9mm 115 gr. The luger functions great, it cycles, and locks open on empty. It appears to hit harder on the left side of the frame.
The second set of 3 pictures is a commercial DWM 1920’s .30 cal.luger I was shooting Fiocchi 93 gr. The luger functions great, it cycles, and locks open on empty. It appears to hit harder on the left side of the frame. I tore the tape on the right side getting it off.
From the way the toggles are hitting, it appears I need new springs? Wolf looks like the best pick, a 38 lb. for the 9mm and a 36lb. for the .30 cal.
I would appreciate any input! From what I have been reading the .30 cal is a hard spring to get to function correctly.
