Yes, fido is right, one can adjust the spring position, but on your system the moving part of the contact points looks like when open it may touch the spring if the spring is adjusted inwards. So the reason for the spring to be touching the mag body may be to avoid it touching the moving points part. Look at the pic2, there is ample clearance, and the spring is not "leaving" the points plate outer circle when points are open or closed. So I'd think the problem is something with your particular brand of points, maybe a (near) pattern that ain't quite right. Pic2 has an original lucas, I have had to throw away pattern points due to all kinds of mismatching (including touching the spring!). At least something to investigate, hope it helps.
