Remembered I just received a Wolf main spring "tune" kit this week.
Each spring is packed individually , so I took them out one at a time and measured:
Nominal Strength All in Inches
by Wolf definition Free Length Wire size O.D. # Turns
36 3.40 0.056 0.393 19
38 3.64 0.056 0.393 19.5
40 3.50 0.056 0.093 19
"extra strenght"
striker spring 2.30 0.028 0.023 18.5
I have no way to determine the compression strenth; but it is
fairly clear the Wolf rating is not at "full compression" in the referenced Luger table, where weights are in the 50-60 lb. range.
I can't explain why the progression from 36, 38, 40 seems out of line, essentially like they mis-labeled the 38 and 40 # springs!
I will email/ call Wolf Monday and ask them!
GT,
I assume, maybe shouldn't, that you used the same ammo when
testing each spring? Could you confirm and also tell us which
ammo you used.
From my other post detailing the hold open vs. ammo, it is clear that any given spring/mag/ammo combination will behave differently. Well, at least it is clear to me.
Check out the firing results starting at post # 16, in this thread:
