I have a problematic Taurus 44 special that suffers a huge amount of light-strikes in DA shooting but shoots fine single action. I pulled the mainspring today and noticed it was shorter than a wolff 12 pounder I had on hand. I replaced the spring and went to the range. Still not working. Does anyone know of a source for extra-power mainsprings or even new standard springs? Everyone seems to carry only reduced power springs. Thanks.
