Seems that modern Pilot Capless pens are equipped with another type of spring, see photo.

Thanks for the update! I hope the new mousetrap like spring survives as long as the original design

Not quite original. The first line of Capless (CS-200, CS-300 etc.) was originally equipped with V-shaped spring. With years, it became loose and nib dried occasionally.
