Hello,
I purchased a pack of Wolff magazine springs: 11# 7-rounders for colt magazines, part #7137x. I tried to replace the spring in one of my Springfield Metalform mags and ran into a problem.
The Wolff spring is considerably longer than the original. Not sure if that is OK or not. Maybe that is how it gets its extra power?
The big issue is how the top of the spring is formed. It doesn't match the angle of the follower and in fact only a tiny portion of the spring will actually touch the follower. Notice how the original spring will fully contact the follower and bends around the notch for the slide release. Also the coils are wound in a reverse fashion. Are these the correct springs or did Wolff send me the wrong ones?
The Wolff spring is on the left and the original Metalform on the right.
